Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469202, here are decompositions:

5 + 31469197 = 31469202
59 + 31469143 = 31469202
71 + 31469131 = 31469202
101 + 31469101 = 31469202
239 + 31468963 = 31469202
283 + 31468919 = 31469202
353 + 31468849 = 31469202
379 + 31468823 = 31469202

Showing the first eight; more decompositions exist.
