Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504176, here are decompositions:

43 + 31504133 = 31504176
47 + 31504129 = 31504176
73 + 31504103 = 31504176
79 + 31504097 = 31504176
89 + 31504087 = 31504176
139 + 31504037 = 31504176
163 + 31504013 = 31504176
199 + 31503977 = 31504176

Showing the first eight; more decompositions exist.
