Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472536, here are decompositions:

47 + 31472489 = 31472536
197 + 31472339 = 31472536
353 + 31472183 = 31472536
383 + 31472153 = 31472536
467 + 31472069 = 31472536
569 + 31471967 = 31472536
653 + 31471883 = 31472536
773 + 31471763 = 31472536

Showing the first eight; more decompositions exist.
