Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86908, here are decompositions:

47 + 86861 = 86908
71 + 86837 = 86908
137 + 86771 = 86908
179 + 86729 = 86908
197 + 86711 = 86908
281 + 86627 = 86908
347 + 86561 = 86908
431 + 86477 = 86908

Showing the first eight; more decompositions exist.
