Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949780, here are decompositions:

3 + 949777 = 949780
47 + 949733 = 949780
89 + 949691 = 949780
107 + 949673 = 949780
113 + 949667 = 949780
131 + 949649 = 949780
137 + 949643 = 949780
149 + 949631 = 949780

Showing the first eight; more decompositions exist.
