Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536302, here are decompositions:

79 + 31536223 = 31536302
241 + 31536061 = 31536302
283 + 31536019 = 31536302
631 + 31535671 = 31536302
709 + 31535593 = 31536302
751 + 31535551 = 31536302
883 + 31535419 = 31536302
991 + 31535311 = 31536302

Showing the first eight; more decompositions exist.
