Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487426, here are decompositions:

3 + 487423 = 487426
29 + 487397 = 487426
113 + 487313 = 487426
179 + 487247 = 487426
239 + 487187 = 487426
293 + 487133 = 487426
347 + 487079 = 487426
353 + 487073 = 487426

Showing the first eight; more decompositions exist.
