Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157766, here are decompositions:
- 19 + 157747 = 157766
- 97 + 157669 = 157766
- 127 + 157639 = 157766
- 139 + 157627 = 157766
- 223 + 157543 = 157766
- 277 + 157489 = 157766
- 283 + 157483 = 157766
- 337 + 157429 = 157766
Showing the first eight; more decompositions exist.
