Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576672, here are decompositions:
- 53 + 31576619 = 31576672
- 89 + 31576583 = 31576672
- 131 + 31576541 = 31576672
- 233 + 31576439 = 31576672
- 263 + 31576409 = 31576672
- 269 + 31576403 = 31576672
- 383 + 31576289 = 31576672
- 389 + 31576283 = 31576672
Showing the first eight; more decompositions exist.
