Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498706, here are decompositions:

3 + 31498703 = 31498706
67 + 31498639 = 31498706
157 + 31498549 = 31498706
193 + 31498513 = 31498706
433 + 31498273 = 31498706
619 + 31498087 = 31498706
709 + 31497997 = 31498706
727 + 31497979 = 31498706

Showing the first eight; more decompositions exist.
