Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487650, here are decompositions:

13 + 487637 = 487650
43 + 487607 = 487650
47 + 487603 = 487650
61 + 487589 = 487650
89 + 487561 = 487650
173 + 487477 = 487650
179 + 487471 = 487650
181 + 487469 = 487650

Showing the first eight; more decompositions exist.
