Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542382, here are decompositions:

5 + 31542377 = 31542382
23 + 31542359 = 31542382
41 + 31542341 = 31542382
59 + 31542323 = 31542382
101 + 31542281 = 31542382
149 + 31542233 = 31542382
233 + 31542149 = 31542382
269 + 31542113 = 31542382

Showing the first eight; more decompositions exist.
