Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539282, here are decompositions:

11 + 31539271 = 31539282
41 + 31539241 = 31539282
53 + 31539229 = 31539282
139 + 31539143 = 31539282
193 + 31539089 = 31539282
199 + 31539083 = 31539282
239 + 31539043 = 31539282
331 + 31538951 = 31539282

Showing the first eight; more decompositions exist.
