Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495232, here are decompositions:

19 + 31495213 = 31495232
61 + 31495171 = 31495232
79 + 31495153 = 31495232
229 + 31495003 = 31495232
283 + 31494949 = 31495232
313 + 31494919 = 31495232
463 + 31494769 = 31495232
541 + 31494691 = 31495232

Showing the first eight; more decompositions exist.
