Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552460, here are decompositions:

31 + 31552429 = 31552460
67 + 31552393 = 31552460
73 + 31552387 = 31552460
109 + 31552351 = 31552460
151 + 31552309 = 31552460
157 + 31552303 = 31552460
223 + 31552237 = 31552460
463 + 31551997 = 31552460

Showing the first eight; more decompositions exist.
