Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514764, here are decompositions:

23 + 31514741 = 31514764
101 + 31514663 = 31514764
137 + 31514627 = 31514764
191 + 31514573 = 31514764
227 + 31514537 = 31514764
251 + 31514513 = 31514764
467 + 31514297 = 31514764
503 + 31514261 = 31514764

Showing the first eight; more decompositions exist.
