Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573126, here are decompositions:

3 + 31573123 = 31573126
17 + 31573109 = 31573126
23 + 31573103 = 31573126
89 + 31573037 = 31573126
257 + 31572869 = 31573126
317 + 31572809 = 31573126
479 + 31572647 = 31573126
593 + 31572533 = 31573126

Showing the first eight; more decompositions exist.
