Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495592, here are decompositions:

3 + 31495589 = 31495592
241 + 31495351 = 31495592
379 + 31495213 = 31495592
421 + 31495171 = 31495592
439 + 31495153 = 31495592
613 + 31494979 = 31495592
643 + 31494949 = 31495592
673 + 31494919 = 31495592

Showing the first eight; more decompositions exist.
