Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006, here are decompositions:
- 23 + 983 = 1006
- 29 + 977 = 1006
- 53 + 953 = 1006
- 59 + 947 = 1006
- 149 + 857 = 1006
- 167 + 839 = 1006
- 179 + 827 = 1006
- 197 + 809 = 1006
Showing the first eight; more decompositions exist.

The digit sequence 1006 first appears in π at position 3,480 of the decimal expansion (the 3,480ordinal-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.
