Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469276, here are decompositions:

37 + 31469239 = 31469276
67 + 31469209 = 31469276
79 + 31469197 = 31469276
283 + 31468993 = 31469276
313 + 31468963 = 31469276
373 + 31468903 = 31469276
499 + 31468777 = 31469276
577 + 31468699 = 31469276

Showing the first eight; more decompositions exist.
