Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484706, here are decompositions:

7 + 31484699 = 31484706
59 + 31484647 = 31484706
79 + 31484627 = 31484706
89 + 31484617 = 31484706
137 + 31484569 = 31484706
163 + 31484543 = 31484706
173 + 31484533 = 31484706
193 + 31484513 = 31484706

Showing the first eight; more decompositions exist.
