Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504002, here are decompositions:

29 + 31503973 = 31504002
31 + 31503971 = 31504002
41 + 31503961 = 31504002
71 + 31503931 = 31504002
73 + 31503929 = 31504002
139 + 31503863 = 31504002
149 + 31503853 = 31504002
191 + 31503811 = 31504002

Showing the first eight; more decompositions exist.
