Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497376, here are decompositions:
- 17 + 31497359 = 31497376
- 23 + 31497353 = 31497376
- 83 + 31497293 = 31497376
- 89 + 31497287 = 31497376
- 293 + 31497083 = 31497376
- 419 + 31496957 = 31497376
- 503 + 31496873 = 31497376
- 557 + 31496819 = 31497376
Showing the first eight; more decompositions exist.
