Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469950, here are decompositions:

47 + 31469903 = 31469950
89 + 31469861 = 31469950
101 + 31469849 = 31469950
137 + 31469813 = 31469950
167 + 31469783 = 31469950
227 + 31469723 = 31469950
389 + 31469561 = 31469950
419 + 31469531 = 31469950

Showing the first eight; more decompositions exist.
