Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552412, here are decompositions:

19 + 31552393 = 31552412
61 + 31552351 = 31552412
103 + 31552309 = 31552412
109 + 31552303 = 31552412
379 + 31552033 = 31552412
433 + 31551979 = 31552412
631 + 31551781 = 31552412
691 + 31551721 = 31552412

Showing the first eight; more decompositions exist.
