Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539264, here are decompositions:

23 + 31539241 = 31539264
73 + 31539191 = 31539264
101 + 31539163 = 31539264
181 + 31539083 = 31539264
191 + 31539073 = 31539264
257 + 31539007 = 31539264
277 + 31538987 = 31539264
313 + 31538951 = 31539264

Showing the first eight; more decompositions exist.
