Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484076, here are decompositions:

5 + 31484071 = 31484076
7 + 31484069 = 31484076
17 + 31484059 = 31484076
97 + 31483979 = 31484076
149 + 31483927 = 31484076
157 + 31483919 = 31484076
163 + 31483913 = 31484076
193 + 31483883 = 31484076

Showing the first eight; more decompositions exist.
