Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471162, here are decompositions:

53 + 31471109 = 31471162
71 + 31471091 = 31471162
83 + 31471079 = 31471162
131 + 31471031 = 31471162
251 + 31470911 = 31471162
293 + 31470869 = 31471162
461 + 31470701 = 31471162
509 + 31470653 = 31471162

Showing the first eight; more decompositions exist.
