Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462612, here are decompositions:

3 + 31462609 = 31462612
23 + 31462589 = 31462612
29 + 31462583 = 31462612
59 + 31462553 = 31462612
131 + 31462481 = 31462612
173 + 31462439 = 31462612
179 + 31462433 = 31462612
239 + 31462373 = 31462612

Showing the first eight; more decompositions exist.
