Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485842, here are decompositions:

3 + 33485839 = 33485842
11 + 33485831 = 33485842
23 + 33485819 = 33485842
53 + 33485789 = 33485842
101 + 33485741 = 33485842
179 + 33485663 = 33485842
359 + 33485483 = 33485842
443 + 33485399 = 33485842

Showing the first eight; more decompositions exist.
