Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620914, here are decompositions:

43 + 31620871 = 31620914
151 + 31620763 = 31620914
163 + 31620751 = 31620914
181 + 31620733 = 31620914
313 + 31620601 = 31620914
337 + 31620577 = 31620914
397 + 31620517 = 31620914
433 + 31620481 = 31620914

Showing the first eight; more decompositions exist.
