Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573338, here are decompositions:

59 + 31573279 = 31573338
61 + 31573277 = 31573338
79 + 31573259 = 31573338
127 + 31573211 = 31573338
149 + 31573189 = 31573338
211 + 31573127 = 31573338
227 + 31573111 = 31573338
229 + 31573109 = 31573338

Showing the first eight; more decompositions exist.
