Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504130, here are decompositions:

3 + 31504127 = 31504130
43 + 31504087 = 31504130
79 + 31504051 = 31504130
157 + 31503973 = 31504130
199 + 31503931 = 31504130
277 + 31503853 = 31504130
283 + 31503847 = 31504130
331 + 31503799 = 31504130

Showing the first eight; more decompositions exist.
