Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495466, here are decompositions:

3 + 31495463 = 31495466
19 + 31495447 = 31495466
43 + 31495423 = 31495466
109 + 31495357 = 31495466
193 + 31495273 = 31495466
313 + 31495153 = 31495466
349 + 31495117 = 31495466
463 + 31495003 = 31495466

Showing the first eight; more decompositions exist.
