Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574166, here are decompositions:

59 + 31574107 = 31574166
67 + 31574099 = 31574166
73 + 31574093 = 31574166
167 + 31573999 = 31574166
199 + 31573967 = 31574166
307 + 31573859 = 31574166
313 + 31573853 = 31574166
347 + 31573819 = 31574166

Showing the first eight; more decompositions exist.
