Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461504, here are decompositions:

17 + 31461487 = 31461504
23 + 31461481 = 31461504
47 + 31461457 = 31461504
101 + 31461403 = 31461504
163 + 31461341 = 31461504
211 + 31461293 = 31461504
223 + 31461281 = 31461504
251 + 31461253 = 31461504

Showing the first eight; more decompositions exist.
