Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471036, here are decompositions:

5 + 31471031 = 31471036
29 + 31471007 = 31471036
59 + 31470977 = 31471036
83 + 31470953 = 31471036
167 + 31470869 = 31471036
173 + 31470863 = 31471036
383 + 31470653 = 31471036
479 + 31470557 = 31471036

Showing the first eight; more decompositions exist.
