Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87398, here are decompositions:

61 + 87337 = 87398
211 + 87187 = 87398
277 + 87121 = 87398
349 + 87049 = 87398
439 + 86959 = 87398
541 + 86857 = 87398
547 + 86851 = 87398
631 + 86767 = 87398

Showing the first eight; more decompositions exist.
