Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537926, here are decompositions:

5 + 31537921 = 31537926
23 + 31537903 = 31537926
37 + 31537889 = 31537926
67 + 31537859 = 31537926
83 + 31537843 = 31537926
89 + 31537837 = 31537926
103 + 31537823 = 31537926
179 + 31537747 = 31537926

Showing the first eight; more decompositions exist.
