Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498054, here are decompositions:

11 + 31498043 = 31498054
47 + 31498007 = 31498054
113 + 31497941 = 31498054
191 + 31497863 = 31498054
227 + 31497827 = 31498054
251 + 31497803 = 31498054
257 + 31497797 = 31498054
281 + 31497773 = 31498054

Showing the first eight; more decompositions exist.
