Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468574, here are decompositions:

3 + 31468571 = 31468574
31 + 31468543 = 31468574
103 + 31468471 = 31468574
127 + 31468447 = 31468574
331 + 31468243 = 31468574
373 + 31468201 = 31468574
547 + 31468027 = 31468574
607 + 31467967 = 31468574

Showing the first eight; more decompositions exist.
