Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468436, here are decompositions:

37 + 31468399 = 31468436
67 + 31468369 = 31468436
193 + 31468243 = 31468436
277 + 31468159 = 31468436
409 + 31468027 = 31468436
487 + 31467949 = 31468436
499 + 31467937 = 31468436
607 + 31467829 = 31468436

Showing the first eight; more decompositions exist.
