Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574200, here are decompositions:

101 + 31574099 = 31574200
107 + 31574093 = 31574200
179 + 31574021 = 31574200
233 + 31573967 = 31574200
239 + 31573961 = 31574200
269 + 31573931 = 31574200
347 + 31573853 = 31574200
353 + 31573847 = 31574200

Showing the first eight; more decompositions exist.
