Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498964, here are decompositions:

67 + 31498897 = 31498964
97 + 31498867 = 31498964
127 + 31498837 = 31498964
151 + 31498813 = 31498964
223 + 31498741 = 31498964
307 + 31498657 = 31498964
373 + 31498591 = 31498964
691 + 31498273 = 31498964

Showing the first eight; more decompositions exist.
