Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539302, here are decompositions:

13 + 31539289 = 31539302
19 + 31539283 = 31539302
31 + 31539271 = 31539302
61 + 31539241 = 31539302
73 + 31539229 = 31539302
139 + 31539163 = 31539302
229 + 31539073 = 31539302
241 + 31539061 = 31539302

Showing the first eight; more decompositions exist.
