Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147437276, here are decompositions:
- 59 + 2147437217 = 2147437276
- 197 + 2147437079 = 2147437276
- 317 + 2147436959 = 2147437276
- 443 + 2147436833 = 2147437276
- 617 + 2147436659 = 2147437276
- 857 + 2147436419 = 2147437276
- 1229 + 2147436047 = 2147437276
- 1289 + 2147435987 = 2147437276
Showing the first eight; more decompositions exist.
