Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504862, here are decompositions:

43 + 31504819 = 31504862
61 + 31504801 = 31504862
79 + 31504783 = 31504862
211 + 31504651 = 31504862
271 + 31504591 = 31504862
409 + 31504453 = 31504862
643 + 31504219 = 31504862
661 + 31504201 = 31504862

Showing the first eight; more decompositions exist.
