Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533906, here are decompositions:

59 + 31533847 = 31533906
67 + 31533839 = 31533906
73 + 31533833 = 31533906
83 + 31533823 = 31533906
137 + 31533769 = 31533906
199 + 31533707 = 31533906
269 + 31533637 = 31533906
293 + 31533613 = 31533906

Showing the first eight; more decompositions exist.
