Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87426, here are decompositions:

5 + 87421 = 87426
19 + 87407 = 87426
23 + 87403 = 87426
43 + 87383 = 87426
67 + 87359 = 87426
89 + 87337 = 87426
103 + 87323 = 87426
109 + 87317 = 87426

Showing the first eight; more decompositions exist.
