Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498664, here are decompositions:

7 + 31498657 = 31498664
73 + 31498591 = 31498664
151 + 31498513 = 31498664
193 + 31498471 = 31498664
541 + 31498123 = 31498664
577 + 31498087 = 31498664
661 + 31498003 = 31498664
733 + 31497931 = 31498664

Showing the first eight; more decompositions exist.
