Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87622, here are decompositions:

83 + 87539 = 87622
113 + 87509 = 87622
131 + 87491 = 87622
149 + 87473 = 87622
179 + 87443 = 87622
239 + 87383 = 87622
263 + 87359 = 87622
401 + 87221 = 87622

Showing the first eight; more decompositions exist.
