Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504074, here are decompositions:

23 + 31504051 = 31504074
37 + 31504037 = 31504074
61 + 31504013 = 31504074
97 + 31503977 = 31504074
101 + 31503973 = 31504074
103 + 31503971 = 31504074
113 + 31503961 = 31504074
157 + 31503917 = 31504074

Showing the first eight; more decompositions exist.
