Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573036, here are decompositions:

29 + 31573007 = 31573036
167 + 31572869 = 31573036
227 + 31572809 = 31573036
389 + 31572647 = 31573036
503 + 31572533 = 31573036
647 + 31572389 = 31573036
773 + 31572263 = 31573036
809 + 31572227 = 31573036

Showing the first eight; more decompositions exist.
