Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504992, here are decompositions:

5 + 31504987 = 31504992
11 + 31504981 = 31504992
41 + 31504951 = 31504992
83 + 31504909 = 31504992
89 + 31504903 = 31504992
109 + 31504883 = 31504992
173 + 31504819 = 31504992
191 + 31504801 = 31504992

Showing the first eight; more decompositions exist.
