Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501446, here are decompositions:

13 + 31501433 = 31501446
19 + 31501427 = 31501446
37 + 31501409 = 31501446
43 + 31501403 = 31501446
47 + 31501399 = 31501446
59 + 31501387 = 31501446
113 + 31501333 = 31501446
199 + 31501247 = 31501446

Showing the first eight; more decompositions exist.
