Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568044, here are decompositions:

3 + 31568041 = 31568044
17 + 31568027 = 31568044
23 + 31568021 = 31568044
83 + 31567961 = 31568044
113 + 31567931 = 31568044
401 + 31567643 = 31568044
491 + 31567553 = 31568044
593 + 31567451 = 31568044

Showing the first eight; more decompositions exist.
