Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931392, here are decompositions:
- 5 + 931387 = 931392
- 29 + 931363 = 931392
- 41 + 931351 = 931392
- 73 + 931319 = 931392
- 79 + 931313 = 931392
- 83 + 931309 = 931392
- 89 + 931303 = 931392
- 103 + 931289 = 931392
Showing the first eight; more decompositions exist.
