Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573702, here are decompositions:

5 + 31573697 = 31573702
23 + 31573679 = 31573702
59 + 31573643 = 31573702
131 + 31573571 = 31573702
179 + 31573523 = 31573702
239 + 31573463 = 31573702
311 + 31573391 = 31573702
443 + 31573259 = 31573702

Showing the first eight; more decompositions exist.
