Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544230, here are decompositions:

17 + 31544213 = 31544230
23 + 31544207 = 31544230
41 + 31544189 = 31544230
59 + 31544171 = 31544230
131 + 31544099 = 31544230
173 + 31544057 = 31544230
191 + 31544039 = 31544230
197 + 31544033 = 31544230

Showing the first eight; more decompositions exist.
