Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495292, here are decompositions:

19 + 31495273 = 31495292
79 + 31495213 = 31495292
139 + 31495153 = 31495292
229 + 31495063 = 31495292
313 + 31494979 = 31495292
349 + 31494943 = 31495292
373 + 31494919 = 31495292
523 + 31494769 = 31495292

Showing the first eight; more decompositions exist.
