Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455068, here are decompositions:

37 + 31455031 = 31455068
97 + 31454971 = 31455068
241 + 31454827 = 31455068
331 + 31454737 = 31455068
367 + 31454701 = 31455068
571 + 31454497 = 31455068
607 + 31454461 = 31455068
691 + 31454377 = 31455068

Showing the first eight; more decompositions exist.
