Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1786, here are decompositions:
- 3 + 1783 = 1786
- 53 + 1733 = 1786
- 89 + 1697 = 1786
- 149 + 1637 = 1786
- 167 + 1619 = 1786
- 173 + 1613 = 1786
- 179 + 1607 = 1786
- 227 + 1559 = 1786
Showing the first eight; more decompositions exist.

The digit sequence 1786 first appears in π at position 1,788 of the decimal expansion (the 1,788ordinal-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.
