Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539554, here are decompositions:

31 + 31539523 = 31539554
223 + 31539331 = 31539554
271 + 31539283 = 31539554
283 + 31539271 = 31539554
313 + 31539241 = 31539554
547 + 31539007 = 31539554
727 + 31538827 = 31539554
811 + 31538743 = 31539554

Showing the first eight; more decompositions exist.
