Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468814, here are decompositions:

37 + 31468777 = 31468814
241 + 31468573 = 31468814
271 + 31468543 = 31468814
367 + 31468447 = 31468814
571 + 31468243 = 31468814
613 + 31468201 = 31468814
787 + 31468027 = 31468814
877 + 31467937 = 31468814

Showing the first eight; more decompositions exist.
