Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472004, here are decompositions:

13 + 31471991 = 31472004
37 + 31471967 = 31472004
71 + 31471933 = 31472004
97 + 31471907 = 31472004
103 + 31471901 = 31472004
173 + 31471831 = 31472004
181 + 31471823 = 31472004
241 + 31471763 = 31472004

Showing the first eight; more decompositions exist.
