Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495636, here are decompositions:

47 + 31495589 = 31495636
113 + 31495523 = 31495636
167 + 31495469 = 31495636
173 + 31495463 = 31495636
233 + 31495403 = 31495636
269 + 31495367 = 31495636
449 + 31495187 = 31495636
479 + 31495157 = 31495636

Showing the first eight; more decompositions exist.
