Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618024, here are decompositions:

23 + 31618001 = 31618024
71 + 31617953 = 31618024
83 + 31617941 = 31618024
197 + 31617827 = 31618024
227 + 31617797 = 31618024
311 + 31617713 = 31618024
461 + 31617563 = 31618024
491 + 31617533 = 31618024

Showing the first eight; more decompositions exist.
