Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552214, here are decompositions:

3 + 31552211 = 31552214
7 + 31552207 = 31552214
157 + 31552057 = 31552214
181 + 31552033 = 31552214
277 + 31551937 = 31552214
313 + 31551901 = 31552214
433 + 31551781 = 31552214
457 + 31551757 = 31552214

Showing the first eight; more decompositions exist.
