Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573662, here are decompositions:

19 + 31573643 = 31573662
23 + 31573639 = 31573662
41 + 31573621 = 31573662
79 + 31573583 = 31573662
101 + 31573561 = 31573662
103 + 31573559 = 31573662
139 + 31573523 = 31573662
149 + 31573513 = 31573662

Showing the first eight; more decompositions exist.
