Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87368, here are decompositions:

31 + 87337 = 87368
157 + 87211 = 87368
181 + 87187 = 87368
331 + 87037 = 87368
409 + 86959 = 87368
439 + 86929 = 87368
499 + 86869 = 87368
601 + 86767 = 87368

Showing the first eight; more decompositions exist.
