Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498764, here are decompositions:

23 + 31498741 = 31498764
61 + 31498703 = 31498764
107 + 31498657 = 31498764
173 + 31498591 = 31498764
223 + 31498541 = 31498764
251 + 31498513 = 31498764
293 + 31498471 = 31498764
337 + 31498427 = 31498764

Showing the first eight; more decompositions exist.
