Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487846, here are decompositions:

3 + 487843 = 487846
17 + 487829 = 487846
53 + 487793 = 487846
89 + 487757 = 487846
113 + 487733 = 487846
137 + 487709 = 487846
197 + 487649 = 487846
239 + 487607 = 487846

Showing the first eight; more decompositions exist.
