Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552384, here are decompositions:

113 + 31552271 = 31552384
131 + 31552253 = 31552384
173 + 31552211 = 31552384
191 + 31552193 = 31552384
257 + 31552127 = 31552384
443 + 31551941 = 31552384
557 + 31551827 = 31552384
701 + 31551683 = 31552384

Showing the first eight; more decompositions exist.
