Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498598, here are decompositions:

7 + 31498591 = 31498598
127 + 31498471 = 31498598
409 + 31498189 = 31498598
487 + 31498111 = 31498598
601 + 31497997 = 31498598
619 + 31497979 = 31498598
727 + 31497871 = 31498598
739 + 31497859 = 31498598

Showing the first eight; more decompositions exist.
