Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504956, here are decompositions:

5 + 31504951 = 31504956
13 + 31504943 = 31504956
47 + 31504909 = 31504956
53 + 31504903 = 31504956
73 + 31504883 = 31504956
83 + 31504873 = 31504956
137 + 31504819 = 31504956
157 + 31504799 = 31504956

Showing the first eight; more decompositions exist.
