Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552112, here are decompositions:

43 + 31552069 = 31552112
79 + 31552033 = 31552112
211 + 31551901 = 31552112
331 + 31551781 = 31552112
379 + 31551733 = 31552112
499 + 31551613 = 31552112
661 + 31551451 = 31552112
751 + 31551361 = 31552112

Showing the first eight; more decompositions exist.
