Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552652, here are decompositions:

13 + 31552639 = 31552652
31 + 31552621 = 31552652
73 + 31552579 = 31552652
163 + 31552489 = 31552652
223 + 31552429 = 31552652
349 + 31552303 = 31552652
619 + 31552033 = 31552652
673 + 31551979 = 31552652

Showing the first eight; more decompositions exist.
