Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504004, here are decompositions:

31 + 31503973 = 31504004
43 + 31503961 = 31504004
73 + 31503931 = 31504004
151 + 31503853 = 31504004
157 + 31503847 = 31504004
163 + 31503841 = 31504004
193 + 31503811 = 31504004
271 + 31503733 = 31504004

Showing the first eight; more decompositions exist.
