Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131494, here are decompositions:
- 5 + 131489 = 131494
- 17 + 131477 = 131494
- 47 + 131447 = 131494
- 53 + 131441 = 131494
- 113 + 131381 = 131494
- 131 + 131363 = 131494
- 137 + 131357 = 131494
- 173 + 131321 = 131494
Showing the first eight; more decompositions exist.
