Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552230, here are decompositions:

19 + 31552211 = 31552230
23 + 31552207 = 31552230
37 + 31552193 = 31552230
103 + 31552127 = 31552230
173 + 31552057 = 31552230
181 + 31552049 = 31552230
197 + 31552033 = 31552230
211 + 31552019 = 31552230

Showing the first eight; more decompositions exist.
