Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85508, here are decompositions:

61 + 85447 = 85508
79 + 85429 = 85508
97 + 85411 = 85508
127 + 85381 = 85508
139 + 85369 = 85508
211 + 85297 = 85508
271 + 85237 = 85508
307 + 85201 = 85508

Showing the first eight; more decompositions exist.
