Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552712, here are decompositions:

3 + 31552709 = 31552712
19 + 31552693 = 31552712
31 + 31552681 = 31552712
73 + 31552639 = 31552712
109 + 31552603 = 31552712
223 + 31552489 = 31552712
283 + 31552429 = 31552712
409 + 31552303 = 31552712

Showing the first eight; more decompositions exist.
