Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569046, here are decompositions:

107 + 31568939 = 31569046
137 + 31568909 = 31569046
149 + 31568897 = 31569046
167 + 31568879 = 31569046
389 + 31568657 = 31569046
503 + 31568543 = 31569046
647 + 31568399 = 31569046
653 + 31568393 = 31569046

Showing the first eight; more decompositions exist.
