Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498042, here are decompositions:

3 + 31498039 = 31498042
101 + 31497941 = 31498042
113 + 31497929 = 31498042
179 + 31497863 = 31498042
239 + 31497803 = 31498042
269 + 31497773 = 31498042
491 + 31497551 = 31498042
593 + 31497449 = 31498042

Showing the first eight; more decompositions exist.
