Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463660, here are decompositions:

73 + 31463587 = 31463660
127 + 31463533 = 31463660
271 + 31463389 = 31463660
307 + 31463353 = 31463660
331 + 31463329 = 31463660
379 + 31463281 = 31463660
433 + 31463227 = 31463660
457 + 31463203 = 31463660

Showing the first eight; more decompositions exist.
