Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681602, here are decompositions:

23 + 8681579 = 8681602
53 + 8681549 = 8681602
89 + 8681513 = 8681602
113 + 8681489 = 8681602
173 + 8681429 = 8681602
233 + 8681369 = 8681602
239 + 8681363 = 8681602
311 + 8681291 = 8681602

Showing the first eight; more decompositions exist.
