Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484010, here are decompositions:

29 + 31483981 = 31484010
31 + 31483979 = 31484010
53 + 31483957 = 31484010
83 + 31483927 = 31484010
97 + 31483913 = 31484010
127 + 31483883 = 31484010
139 + 31483871 = 31484010
149 + 31483861 = 31484010

Showing the first eight; more decompositions exist.
