Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498928, here are decompositions:

31 + 31498897 = 31498928
61 + 31498867 = 31498928
79 + 31498849 = 31498928
271 + 31498657 = 31498928
337 + 31498591 = 31498928
379 + 31498549 = 31498928
457 + 31498471 = 31498928
739 + 31498189 = 31498928

Showing the first eight; more decompositions exist.
