Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498844, here are decompositions:

7 + 31498837 = 31498844
31 + 31498813 = 31498844
103 + 31498741 = 31498844
331 + 31498513 = 31498844
373 + 31498471 = 31498844
571 + 31498273 = 31498844
631 + 31498213 = 31498844
733 + 31498111 = 31498844

Showing the first eight; more decompositions exist.
