Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552202, here are decompositions:

223 + 31551979 = 31552202
349 + 31551853 = 31552202
421 + 31551781 = 31552202
751 + 31551451 = 31552202
853 + 31551349 = 31552202
883 + 31551319 = 31552202
919 + 31551283 = 31552202
1051 + 31551151 = 31552202

Showing the first eight; more decompositions exist.
