Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484700, here are decompositions:
- 53 + 31484647 = 31484700
- 73 + 31484627 = 31484700
- 83 + 31484617 = 31484700
- 131 + 31484569 = 31484700
- 157 + 31484543 = 31484700
- 167 + 31484533 = 31484700
- 197 + 31484503 = 31484700
- 239 + 31484461 = 31484700
Showing the first eight; more decompositions exist.
