Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534690, here are decompositions:
- 53 + 31534637 = 31534690
- 59 + 31534631 = 31534690
- 101 + 31534589 = 31534690
- 137 + 31534553 = 31534690
- 197 + 31534493 = 31534690
- 233 + 31534457 = 31534690
- 263 + 31534427 = 31534690
- 347 + 31534343 = 31534690
Showing the first eight; more decompositions exist.
