Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498060, here are decompositions:

17 + 31498043 = 31498060
53 + 31498007 = 31498060
131 + 31497929 = 31498060
197 + 31497863 = 31498060
233 + 31497827 = 31498060
257 + 31497803 = 31498060
263 + 31497797 = 31498060
353 + 31497707 = 31498060

Showing the first eight; more decompositions exist.
