Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161774, here are decompositions:
- 3 + 161771 = 161774
- 13 + 161761 = 161774
- 31 + 161743 = 161774
- 43 + 161731 = 161774
- 163 + 161611 = 161774
- 211 + 161563 = 161774
- 271 + 161503 = 161774
- 313 + 161461 = 161774
Showing the first eight; more decompositions exist.
