Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483242, here are decompositions:

5 + 31483237 = 31483242
13 + 31483229 = 31483242
29 + 31483213 = 31483242
73 + 31483169 = 31483242
79 + 31483163 = 31483242
149 + 31483093 = 31483242
173 + 31483069 = 31483242
181 + 31483061 = 31483242

Showing the first eight; more decompositions exist.
