Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471926, here are decompositions:

19 + 31471907 = 31471926
43 + 31471883 = 31471926
103 + 31471823 = 31471926
127 + 31471799 = 31471926
139 + 31471787 = 31471926
163 + 31471763 = 31471926
223 + 31471703 = 31471926
229 + 31471697 = 31471926

Showing the first eight; more decompositions exist.
