Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573088, here are decompositions:

31 + 31573057 = 31573088
61 + 31573027 = 31573088
67 + 31573021 = 31573088
109 + 31572979 = 31573088
139 + 31572949 = 31573088
439 + 31572649 = 31573088
499 + 31572589 = 31573088
577 + 31572511 = 31573088

Showing the first eight; more decompositions exist.
