Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542592, here are decompositions:

5 + 31542587 = 31542592
83 + 31542509 = 31542592
113 + 31542479 = 31542592
173 + 31542419 = 31542592
233 + 31542359 = 31542592
251 + 31542341 = 31542592
269 + 31542323 = 31542592
311 + 31542281 = 31542592

Showing the first eight; more decompositions exist.
