Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498234, here are decompositions:

17 + 31498217 = 31498234
41 + 31498193 = 31498234
83 + 31498151 = 31498234
191 + 31498043 = 31498234
227 + 31498007 = 31498234
293 + 31497941 = 31498234
431 + 31497803 = 31498234
461 + 31497773 = 31498234

Showing the first eight; more decompositions exist.
