Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495382, here are decompositions:

31 + 31495351 = 31495382
109 + 31495273 = 31495382
211 + 31495171 = 31495382
229 + 31495153 = 31495382
379 + 31495003 = 31495382
433 + 31494949 = 31495382
439 + 31494943 = 31495382
463 + 31494919 = 31495382

Showing the first eight; more decompositions exist.
