Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552560, here are decompositions:

7 + 31552553 = 31552560
23 + 31552537 = 31552560
71 + 31552489 = 31552560
73 + 31552487 = 31552560
131 + 31552429 = 31552560
139 + 31552421 = 31552560
157 + 31552403 = 31552560
167 + 31552393 = 31552560

Showing the first eight; more decompositions exist.
