Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573746, here are decompositions:

67 + 31573679 = 31573746
103 + 31573643 = 31573746
107 + 31573639 = 31573746
163 + 31573583 = 31573746
223 + 31573523 = 31573746
233 + 31573513 = 31573746
283 + 31573463 = 31573746
353 + 31573393 = 31573746

Showing the first eight; more decompositions exist.
