Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542496, here are decompositions:

17 + 31542479 = 31542496
59 + 31542437 = 31542496
137 + 31542359 = 31542496
173 + 31542323 = 31542496
263 + 31542233 = 31542496
347 + 31542149 = 31542496
383 + 31542113 = 31542496
563 + 31541933 = 31542496

Showing the first eight; more decompositions exist.
