Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498926, here are decompositions:

13 + 31498913 = 31498926
29 + 31498897 = 31498926
47 + 31498879 = 31498926
59 + 31498867 = 31498926
73 + 31498853 = 31498926
79 + 31498847 = 31498926
89 + 31498837 = 31498926
97 + 31498829 = 31498926

Showing the first eight; more decompositions exist.
