Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535478, here are decompositions:
- 11 + 31535467 = 31535478
- 59 + 31535419 = 31535478
- 61 + 31535417 = 31535478
- 67 + 31535411 = 31535478
- 97 + 31535381 = 31535478
- 101 + 31535377 = 31535478
- 137 + 31535341 = 31535478
- 151 + 31535327 = 31535478
Showing the first eight; more decompositions exist.
