Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568014, here are decompositions:

53 + 31567961 = 31568014
83 + 31567931 = 31568014
131 + 31567883 = 31568014
461 + 31567553 = 31568014
503 + 31567511 = 31568014
563 + 31567451 = 31568014
587 + 31567427 = 31568014
617 + 31567397 = 31568014

Showing the first eight; more decompositions exist.
