Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502356, here are decompositions:
- 3 + 31502353 = 31502356
- 23 + 31502333 = 31502356
- 113 + 31502243 = 31502356
- 167 + 31502189 = 31502356
- 173 + 31502183 = 31502356
- 227 + 31502129 = 31502356
- 257 + 31502099 = 31502356
- 419 + 31501937 = 31502356
Showing the first eight; more decompositions exist.
