Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484850, here are decompositions:

11 + 31484839 = 31484850
13 + 31484837 = 31484850
29 + 31484821 = 31484850
53 + 31484797 = 31484850
73 + 31484777 = 31484850
79 + 31484771 = 31484850
97 + 31484753 = 31484850
109 + 31484741 = 31484850

Showing the first eight; more decompositions exist.
