Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618654, here are decompositions:

17 + 31618637 = 31618654
107 + 31618547 = 31618654
191 + 31618463 = 31618654
251 + 31618403 = 31618654
293 + 31618361 = 31618654
443 + 31618211 = 31618654
461 + 31618193 = 31618654
467 + 31618187 = 31618654

Showing the first eight; more decompositions exist.
