Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535424, here are decompositions:
- 5 + 31535419 = 31535424
- 7 + 31535417 = 31535424
- 13 + 31535411 = 31535424
- 43 + 31535381 = 31535424
- 47 + 31535377 = 31535424
- 83 + 31535341 = 31535424
- 97 + 31535327 = 31535424
- 103 + 31535321 = 31535424
Showing the first eight; more decompositions exist.
