Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573626, here are decompositions:

5 + 31573621 = 31573626
43 + 31573583 = 31573626
67 + 31573559 = 31573626
103 + 31573523 = 31573626
113 + 31573513 = 31573626
127 + 31573499 = 31573626
163 + 31573463 = 31573626
199 + 31573427 = 31573626

Showing the first eight; more decompositions exist.
