Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552646, here are decompositions:

3 + 31552643 = 31552646
7 + 31552639 = 31552646
43 + 31552603 = 31552646
67 + 31552579 = 31552646
109 + 31552537 = 31552646
157 + 31552489 = 31552646
337 + 31552309 = 31552646
409 + 31552237 = 31552646

Showing the first eight; more decompositions exist.
