Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461506, here are decompositions:

19 + 31461487 = 31461506
79 + 31461427 = 31461506
103 + 31461403 = 31461506
157 + 31461349 = 31461506
163 + 31461343 = 31461506
277 + 31461229 = 31461506
283 + 31461223 = 31461506
313 + 31461193 = 31461506

Showing the first eight; more decompositions exist.
