Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31004, here are decompositions:

67 + 30937 = 31004
73 + 30931 = 31004
151 + 30853 = 31004
163 + 30841 = 31004
223 + 30781 = 31004
241 + 30763 = 31004
277 + 30727 = 31004
307 + 30697 = 31004

Showing the first eight; more decompositions exist.
