Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552012, here are decompositions:

53 + 31551959 = 31552012
71 + 31551941 = 31552012
383 + 31551629 = 31552012
419 + 31551593 = 31552012
509 + 31551503 = 31552012
599 + 31551413 = 31552012
659 + 31551353 = 31552012
683 + 31551329 = 31552012

Showing the first eight; more decompositions exist.
