Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589162, here are decompositions:

43 + 31589119 = 31589162
151 + 31589011 = 31589162
211 + 31588951 = 31589162
229 + 31588933 = 31589162
349 + 31588813 = 31589162
463 + 31588699 = 31589162
601 + 31588561 = 31589162
691 + 31588471 = 31589162

Showing the first eight; more decompositions exist.
