Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465844, here are decompositions:

13 + 31465831 = 31465844
43 + 31465801 = 31465844
97 + 31465747 = 31465844
103 + 31465741 = 31465844
181 + 31465663 = 31465844
283 + 31465561 = 31465844
523 + 31465321 = 31465844
601 + 31465243 = 31465844

Showing the first eight; more decompositions exist.
