Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541528, here are decompositions:

19 + 31541509 = 31541528
61 + 31541467 = 31541528
79 + 31541449 = 31541528
127 + 31541401 = 31541528
181 + 31541347 = 31541528
349 + 31541179 = 31541528
367 + 31541161 = 31541528
457 + 31541071 = 31541528

Showing the first eight; more decompositions exist.
