Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506514, here are decompositions:

3 + 31506511 = 31506514
71 + 31506443 = 31506514
251 + 31506263 = 31506514
443 + 31506071 = 31506514
521 + 31505993 = 31506514
587 + 31505927 = 31506514
593 + 31505921 = 31506514
701 + 31505813 = 31506514

Showing the first eight; more decompositions exist.
