Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540600, here are decompositions:
- 71 + 31540529 = 31540600
- 101 + 31540499 = 31540600
- 107 + 31540493 = 31540600
- 257 + 31540343 = 31540600
- 359 + 31540241 = 31540600
- 383 + 31540217 = 31540600
- 389 + 31540211 = 31540600
- 419 + 31540181 = 31540600
Showing the first eight; more decompositions exist.
