Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539462, here are decompositions:

23 + 31539439 = 31539462
41 + 31539421 = 31539462
61 + 31539401 = 31539462
109 + 31539353 = 31539462
113 + 31539349 = 31539462
131 + 31539331 = 31539462
173 + 31539289 = 31539462
179 + 31539283 = 31539462

Showing the first eight; more decompositions exist.
