Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542712, here are decompositions:

53 + 31542659 = 31542712
233 + 31542479 = 31542712
293 + 31542419 = 31542712
353 + 31542359 = 31542712
389 + 31542323 = 31542712
431 + 31542281 = 31542712
479 + 31542233 = 31542712
563 + 31542149 = 31542712

Showing the first eight; more decompositions exist.
