Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495586, here are decompositions:

139 + 31495447 = 31495586
163 + 31495423 = 31495586
229 + 31495357 = 31495586
313 + 31495273 = 31495586
373 + 31495213 = 31495586
433 + 31495153 = 31495586
439 + 31495147 = 31495586
523 + 31495063 = 31495586

Showing the first eight; more decompositions exist.
