Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499780, here are decompositions:

41 + 499739 = 499780
89 + 499691 = 499780
101 + 499679 = 499780
107 + 499673 = 499780
131 + 499649 = 499780
173 + 499607 = 499780
179 + 499601 = 499780
257 + 499523 = 499780

Showing the first eight; more decompositions exist.
