Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592892, here are decompositions:

43 + 31592849 = 31592892
59 + 31592833 = 31592892
83 + 31592809 = 31592892
113 + 31592779 = 31592892
131 + 31592761 = 31592892
229 + 31592663 = 31592892
241 + 31592651 = 31592892
251 + 31592641 = 31592892

Showing the first eight; more decompositions exist.
