Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603004, here are decompositions:

31 + 31602973 = 31603004
73 + 31602931 = 31603004
127 + 31602877 = 31603004
151 + 31602853 = 31603004
211 + 31602793 = 31603004
241 + 31602763 = 31603004
313 + 31602691 = 31603004
331 + 31602673 = 31603004

Showing the first eight; more decompositions exist.
