Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476684, here are decompositions:
- 53 + 31476631 = 31476684
- 61 + 31476623 = 31476684
- 73 + 31476611 = 31476684
- 97 + 31476587 = 31476684
- 137 + 31476547 = 31476684
- 167 + 31476517 = 31476684
- 223 + 31476461 = 31476684
- 227 + 31476457 = 31476684
Showing the first eight; more decompositions exist.
