Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573792, here are decompositions:

113 + 31573679 = 31573792
149 + 31573643 = 31573792
233 + 31573559 = 31573792
269 + 31573523 = 31573792
293 + 31573499 = 31573792
401 + 31573391 = 31573792
431 + 31573361 = 31573792
641 + 31573151 = 31573792

Showing the first eight; more decompositions exist.
