Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487802, here are decompositions:

13 + 487789 = 487802
19 + 487783 = 487802
61 + 487741 = 487802
151 + 487651 = 487802
199 + 487603 = 487802
241 + 487561 = 487802
313 + 487489 = 487802
331 + 487471 = 487802

Showing the first eight; more decompositions exist.
