Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550854, here are decompositions:

3 + 31550851 = 31550854
17 + 31550837 = 31550854
47 + 31550807 = 31550854
53 + 31550801 = 31550854
107 + 31550747 = 31550854
131 + 31550723 = 31550854
173 + 31550681 = 31550854
227 + 31550627 = 31550854

Showing the first eight; more decompositions exist.
