Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552680, here are decompositions:

37 + 31552643 = 31552680
41 + 31552639 = 31552680
59 + 31552621 = 31552680
101 + 31552579 = 31552680
127 + 31552553 = 31552680
191 + 31552489 = 31552680
193 + 31552487 = 31552680
251 + 31552429 = 31552680

Showing the first eight; more decompositions exist.
