Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498904, here are decompositions:

7 + 31498897 = 31498904
37 + 31498867 = 31498904
67 + 31498837 = 31498904
163 + 31498741 = 31498904
313 + 31498591 = 31498904
433 + 31498471 = 31498904
631 + 31498273 = 31498904
691 + 31498213 = 31498904

Showing the first eight; more decompositions exist.
