Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539292, here are decompositions:

3 + 31539289 = 31539292
101 + 31539191 = 31539292
149 + 31539143 = 31539292
503 + 31538789 = 31539292
563 + 31538729 = 31539292
599 + 31538693 = 31539292
881 + 31538411 = 31539292
1031 + 31538261 = 31539292

Showing the first eight; more decompositions exist.
