Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573602, here are decompositions:

19 + 31573583 = 31573602
31 + 31573571 = 31573602
41 + 31573561 = 31573602
43 + 31573559 = 31573602
79 + 31573523 = 31573602
89 + 31573513 = 31573602
101 + 31573501 = 31573602
103 + 31573499 = 31573602

Showing the first eight; more decompositions exist.
