Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503962, here are decompositions:
- 31 + 31503931 = 31503962
- 79 + 31503883 = 31503962
- 109 + 31503853 = 31503962
- 151 + 31503811 = 31503962
- 163 + 31503799 = 31503962
- 211 + 31503751 = 31503962
- 229 + 31503733 = 31503962
- 331 + 31503631 = 31503962
Showing the first eight; more decompositions exist.
