Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484910, here are decompositions:

7 + 31484903 = 31484910
47 + 31484863 = 31484910
71 + 31484839 = 31484910
73 + 31484837 = 31484910
89 + 31484821 = 31484910
109 + 31484801 = 31484910
113 + 31484797 = 31484910
139 + 31484771 = 31484910

Showing the first eight; more decompositions exist.
