Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573622, here are decompositions:

61 + 31573561 = 31573622
109 + 31573513 = 31573622
229 + 31573393 = 31573622
433 + 31573189 = 31573622
499 + 31573123 = 31573622
601 + 31573021 = 31573622
643 + 31572979 = 31573622
673 + 31572949 = 31573622

Showing the first eight; more decompositions exist.
