Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533846, here are decompositions:

7 + 31533839 = 31533846
13 + 31533833 = 31533846
17 + 31533829 = 31533846
23 + 31533823 = 31533846
73 + 31533773 = 31533846
83 + 31533763 = 31533846
139 + 31533707 = 31533846
233 + 31533613 = 31533846

Showing the first eight; more decompositions exist.
