Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523778, here are decompositions:

19 + 33523759 = 33523778
109 + 33523669 = 33523778
199 + 33523579 = 33523778
331 + 33523447 = 33523778
367 + 33523411 = 33523778
397 + 33523381 = 33523778
487 + 33523291 = 33523778
751 + 33523027 = 33523778

Showing the first eight; more decompositions exist.
