Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498174, here are decompositions:

23 + 31498151 = 31498174
131 + 31498043 = 31498174
167 + 31498007 = 31498174
233 + 31497941 = 31498174
311 + 31497863 = 31498174
347 + 31497827 = 31498174
401 + 31497773 = 31498174
467 + 31497707 = 31498174

Showing the first eight; more decompositions exist.
