Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594848, here are decompositions:

37 + 31594811 = 31594848
41 + 31594807 = 31594848
79 + 31594769 = 31594848
101 + 31594747 = 31594848
149 + 31594699 = 31594848
157 + 31594691 = 31594848
167 + 31594681 = 31594848
239 + 31594609 = 31594848

Showing the first eight; more decompositions exist.
