Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87628, here are decompositions:

5 + 87623 = 87628
41 + 87587 = 87628
71 + 87557 = 87628
89 + 87539 = 87628
137 + 87491 = 87628
269 + 87359 = 87628
311 + 87317 = 87628
347 + 87281 = 87628

Showing the first eight; more decompositions exist.
