Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542364, here are decompositions:

5 + 31542359 = 31542364
23 + 31542341 = 31542364
41 + 31542323 = 31542364
83 + 31542281 = 31542364
131 + 31542233 = 31542364
167 + 31542197 = 31542364
251 + 31542113 = 31542364
281 + 31542083 = 31542364

Showing the first eight; more decompositions exist.
