Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479164, here are decompositions:

37 + 31479127 = 31479164
103 + 31479061 = 31479164
163 + 31479001 = 31479164
181 + 31478983 = 31479164
313 + 31478851 = 31479164
463 + 31478701 = 31479164
571 + 31478593 = 31479164
643 + 31478521 = 31479164

Showing the first eight; more decompositions exist.
