Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504010, here are decompositions:

37 + 31503973 = 31504010
79 + 31503931 = 31504010
127 + 31503883 = 31504010
157 + 31503853 = 31504010
163 + 31503847 = 31504010
199 + 31503811 = 31504010
211 + 31503799 = 31504010
277 + 31503733 = 31504010

Showing the first eight; more decompositions exist.
