Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539274, here are decompositions:

3 + 31539271 = 31539274
83 + 31539191 = 31539274
131 + 31539143 = 31539274
191 + 31539083 = 31539274
227 + 31539047 = 31539274
467 + 31538807 = 31539274
521 + 31538753 = 31539274
563 + 31538711 = 31539274

Showing the first eight; more decompositions exist.
