Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66418, here are decompositions:
- 5 + 66413 = 66418
- 41 + 66377 = 66418
- 59 + 66359 = 66418
- 71 + 66347 = 66418
- 179 + 66239 = 66418
- 197 + 66221 = 66418
- 227 + 66191 = 66418
- 239 + 66179 = 66418
Showing the first eight; more decompositions exist.

The digit sequence 66418 first appears in π at position 104,336 of the decimal expansion (the 104,336ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
