Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552982, here are decompositions:

103 + 31552879 = 31552982
151 + 31552831 = 31552982
379 + 31552603 = 31552982
631 + 31552351 = 31552982
673 + 31552309 = 31552982
1123 + 31551859 = 31552982
1129 + 31551853 = 31552982
1201 + 31551781 = 31552982

Showing the first eight; more decompositions exist.
