Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504112, here are decompositions:

61 + 31504051 = 31504112
139 + 31503973 = 31504112
151 + 31503961 = 31504112
181 + 31503931 = 31504112
229 + 31503883 = 31504112
271 + 31503841 = 31504112
313 + 31503799 = 31504112
379 + 31503733 = 31504112

Showing the first eight; more decompositions exist.
