Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498826, here are decompositions:

13 + 31498813 = 31498826
277 + 31498549 = 31498826
313 + 31498513 = 31498826
547 + 31498279 = 31498826
613 + 31498213 = 31498826
739 + 31498087 = 31498826
757 + 31498069 = 31498826
787 + 31498039 = 31498826

Showing the first eight; more decompositions exist.
