Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495952, here are decompositions:

3 + 31495949 = 31495952
31 + 31495921 = 31495952
73 + 31495879 = 31495952
151 + 31495801 = 31495952
199 + 31495753 = 31495952
211 + 31495741 = 31495952
223 + 31495729 = 31495952
349 + 31495603 = 31495952

Showing the first eight; more decompositions exist.
