Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487670, here are decompositions:

13 + 487657 = 487670
19 + 487651 = 487670
67 + 487603 = 487670
109 + 487561 = 487670
163 + 487507 = 487670
181 + 487489 = 487670
193 + 487477 = 487670
199 + 487471 = 487670

Showing the first eight; more decompositions exist.
