Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131746, here are decompositions:
- 3 + 131743 = 131746
- 59 + 131687 = 131746
- 107 + 131639 = 131746
- 227 + 131519 = 131746
- 239 + 131507 = 131746
- 257 + 131489 = 131746
- 269 + 131477 = 131746
- 383 + 131363 = 131746
Showing the first eight; more decompositions exist.
