Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498246, here are decompositions:

29 + 31498217 = 31498246
47 + 31498199 = 31498246
53 + 31498193 = 31498246
239 + 31498007 = 31498246
317 + 31497929 = 31498246
383 + 31497863 = 31498246
419 + 31497827 = 31498246
443 + 31497803 = 31498246

Showing the first eight; more decompositions exist.
