Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589746, here are decompositions:

53 + 31589693 = 31589746
113 + 31589633 = 31589746
179 + 31589567 = 31589746
233 + 31589513 = 31589746
263 + 31589483 = 31589746
443 + 31589303 = 31589746
449 + 31589297 = 31589746
563 + 31589183 = 31589746

Showing the first eight; more decompositions exist.
