Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523642, here are decompositions:

41 + 33523601 = 33523642
59 + 33523583 = 33523642
179 + 33523463 = 33523642
233 + 33523409 = 33523642
263 + 33523379 = 33523642
389 + 33523253 = 33523642
401 + 33523241 = 33523642
431 + 33523211 = 33523642

Showing the first eight; more decompositions exist.
