Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461576, here are decompositions:

5 + 31461571 = 31461576
7 + 31461569 = 31461576
19 + 31461557 = 31461576
23 + 31461553 = 31461576
43 + 31461533 = 31461576
53 + 31461523 = 31461576
59 + 31461517 = 31461576
89 + 31461487 = 31461576

Showing the first eight; more decompositions exist.
