Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577204, here are decompositions:

7 + 31577197 = 31577204
31 + 31577173 = 31577204
73 + 31577131 = 31577204
151 + 31577053 = 31577204
313 + 31576891 = 31577204
523 + 31576681 = 31577204
727 + 31576477 = 31577204
751 + 31576453 = 31577204

Showing the first eight; more decompositions exist.
