Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505104, here are decompositions:

5 + 31505099 = 31505104
23 + 31505081 = 31505104
101 + 31505003 = 31505104
401 + 31504703 = 31505104
443 + 31504661 = 31505104
557 + 31504547 = 31505104
971 + 31504133 = 31505104
977 + 31504127 = 31505104

Showing the first eight; more decompositions exist.
