Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539382, here are decompositions:

5 + 31539377 = 31539382
29 + 31539353 = 31539382
53 + 31539329 = 31539382
191 + 31539191 = 31539382
239 + 31539143 = 31539382
293 + 31539089 = 31539382
431 + 31538951 = 31539382
593 + 31538789 = 31539382

Showing the first eight; more decompositions exist.
