Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542718, here are decompositions:

41 + 31542677 = 31542718
59 + 31542659 = 31542718
131 + 31542587 = 31542718
239 + 31542479 = 31542718
281 + 31542437 = 31542718
359 + 31542359 = 31542718
521 + 31542197 = 31542718
569 + 31542149 = 31542718

Showing the first eight; more decompositions exist.
