Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505096, here are decompositions:

19 + 31505077 = 31505096
97 + 31504999 = 31505096
109 + 31504987 = 31505096
193 + 31504903 = 31505096
223 + 31504873 = 31505096
277 + 31504819 = 31505096
313 + 31504783 = 31505096
349 + 31504747 = 31505096

Showing the first eight; more decompositions exist.
