Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761630, here are decompositions:

11 + 8761619 = 8761630
29 + 8761601 = 8761630
83 + 8761547 = 8761630
113 + 8761517 = 8761630
167 + 8761463 = 8761630
173 + 8761457 = 8761630
191 + 8761439 = 8761630
197 + 8761433 = 8761630

Showing the first eight; more decompositions exist.
