Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535644, here are decompositions:
- 5 + 31535639 = 31535644
- 11 + 31535633 = 31535644
- 53 + 31535591 = 31535644
- 227 + 31535417 = 31535644
- 233 + 31535411 = 31535644
- 263 + 31535381 = 31535644
- 317 + 31535327 = 31535644
- 431 + 31535213 = 31535644
Showing the first eight; more decompositions exist.
