Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469176, here are decompositions:

107 + 31469069 = 31469176
149 + 31469027 = 31469176
257 + 31468919 = 31469176
353 + 31468823 = 31469176
383 + 31468793 = 31469176
419 + 31468757 = 31469176
449 + 31468727 = 31469176
509 + 31468667 = 31469176

Showing the first eight; more decompositions exist.
