Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552760, here are decompositions:

13 + 31552747 = 31552760
67 + 31552693 = 31552760
79 + 31552681 = 31552760
139 + 31552621 = 31552760
157 + 31552603 = 31552760
181 + 31552579 = 31552760
223 + 31552537 = 31552760
271 + 31552489 = 31552760

Showing the first eight; more decompositions exist.
