Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87718, here are decompositions:

17 + 87701 = 87718
47 + 87671 = 87718
89 + 87629 = 87718
131 + 87587 = 87718
179 + 87539 = 87718
227 + 87491 = 87718
311 + 87407 = 87718
359 + 87359 = 87718

Showing the first eight; more decompositions exist.
