Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573336, here are decompositions:

59 + 31573277 = 31573336
83 + 31573253 = 31573336
173 + 31573163 = 31573336
227 + 31573109 = 31573336
233 + 31573103 = 31573336
467 + 31572869 = 31573336
947 + 31572389 = 31573336
1013 + 31572323 = 31573336

Showing the first eight; more decompositions exist.
