Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502004, here are decompositions:

47 + 31501957 = 31502004
67 + 31501937 = 31502004
97 + 31501907 = 31502004
173 + 31501831 = 31502004
181 + 31501823 = 31502004
197 + 31501807 = 31502004
223 + 31501781 = 31502004
263 + 31501741 = 31502004

Showing the first eight; more decompositions exist.
