Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521094, here are decompositions:

41 + 31521053 = 31521094
197 + 31520897 = 31521094
233 + 31520861 = 31521094
257 + 31520837 = 31521094
347 + 31520747 = 31521094
467 + 31520627 = 31521094
557 + 31520537 = 31521094
641 + 31520453 = 31521094

Showing the first eight; more decompositions exist.
