Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527914, here are decompositions:

97 + 31527817 = 31527914
127 + 31527787 = 31527914
211 + 31527703 = 31527914
331 + 31527583 = 31527914
337 + 31527577 = 31527914
373 + 31527541 = 31527914
433 + 31527481 = 31527914
571 + 31527343 = 31527914

Showing the first eight; more decompositions exist.
