Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33495642, here are decompositions:

73 + 33495569 = 33495642
139 + 33495503 = 33495642
179 + 33495463 = 33495642
223 + 33495419 = 33495642
239 + 33495403 = 33495642
251 + 33495391 = 33495642
419 + 33495223 = 33495642
431 + 33495211 = 33495642

Showing the first eight; more decompositions exist.
