Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469236, here are decompositions:

59 + 31469177 = 31469236
167 + 31469069 = 31469236
269 + 31468967 = 31469236
317 + 31468919 = 31469236
443 + 31468793 = 31469236
479 + 31468757 = 31469236
509 + 31468727 = 31469236
569 + 31468667 = 31469236

Showing the first eight; more decompositions exist.
