Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498604, here are decompositions:

13 + 31498591 = 31498604
331 + 31498273 = 31498604
601 + 31498003 = 31498604
607 + 31497997 = 31498604
673 + 31497931 = 31498604
733 + 31497871 = 31498604
853 + 31497751 = 31498604
877 + 31497727 = 31498604

Showing the first eight; more decompositions exist.
