Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500296, here are decompositions:

103 + 31500193 = 31500296
109 + 31500187 = 31500296
307 + 31499989 = 31500296
397 + 31499899 = 31500296
433 + 31499863 = 31500296
463 + 31499833 = 31500296
829 + 31499467 = 31500296
967 + 31499329 = 31500296

Showing the first eight; more decompositions exist.
