Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552854, here are decompositions:

7 + 31552847 = 31552854
23 + 31552831 = 31552854
37 + 31552817 = 31552854
107 + 31552747 = 31552854
127 + 31552727 = 31552854
173 + 31552681 = 31552854
211 + 31552643 = 31552854
233 + 31552621 = 31552854

Showing the first eight; more decompositions exist.
