Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484202, here are decompositions:

23 + 31484179 = 31484202
41 + 31484161 = 31484202
59 + 31484143 = 31484202
73 + 31484129 = 31484202
109 + 31484093 = 31484202
131 + 31484071 = 31484202
223 + 31483979 = 31484202
283 + 31483919 = 31484202

Showing the first eight; more decompositions exist.
