Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505036, here are decompositions:

37 + 31504999 = 31505036
127 + 31504909 = 31505036
163 + 31504873 = 31505036
463 + 31504573 = 31505036
709 + 31504327 = 31505036
733 + 31504303 = 31505036
853 + 31504183 = 31505036
907 + 31504129 = 31505036

Showing the first eight; more decompositions exist.
