Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472778, here are decompositions:

7 + 33472771 = 33472778
19 + 33472759 = 33472778
109 + 33472669 = 33472778
139 + 33472639 = 33472778
439 + 33472339 = 33472778
541 + 33472237 = 33472778
571 + 33472207 = 33472778
631 + 33472147 = 33472778

Showing the first eight; more decompositions exist.
