Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552124, here are decompositions:

67 + 31552057 = 31552124
127 + 31551997 = 31552124
223 + 31551901 = 31552124
271 + 31551853 = 31552124
367 + 31551757 = 31552124
547 + 31551577 = 31552124
577 + 31551547 = 31552124
607 + 31551517 = 31552124

Showing the first eight; more decompositions exist.
