Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543066, here are decompositions:

47 + 31543019 = 31543066
239 + 31542827 = 31543066
257 + 31542809 = 31543066
389 + 31542677 = 31543066
479 + 31542587 = 31543066
557 + 31542509 = 31543066
587 + 31542479 = 31543066
647 + 31542419 = 31543066

Showing the first eight; more decompositions exist.
