Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949890, here are decompositions:

37 + 949853 = 949890
41 + 949849 = 949890
79 + 949811 = 949890
101 + 949789 = 949890
113 + 949777 = 949890
131 + 949759 = 949890
157 + 949733 = 949890
191 + 949699 = 949890

Showing the first eight; more decompositions exist.
