Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502224, here are decompositions:
- 11 + 31502213 = 31502224
- 41 + 31502183 = 31502224
- 311 + 31501913 = 31502224
- 317 + 31501907 = 31502224
- 401 + 31501823 = 31502224
- 443 + 31501781 = 31502224
- 503 + 31501721 = 31502224
- 563 + 31501661 = 31502224
Showing the first eight; more decompositions exist.
