Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460798, here are decompositions:

7 + 31460791 = 31460798
97 + 31460701 = 31460798
151 + 31460647 = 31460798
307 + 31460491 = 31460798
367 + 31460431 = 31460798
601 + 31460197 = 31460798
631 + 31460167 = 31460798
661 + 31460137 = 31460798

Showing the first eight; more decompositions exist.
