Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487778, here are decompositions:

7 + 33487771 = 33487778
19 + 33487759 = 33487778
61 + 33487717 = 33487778
97 + 33487681 = 33487778
127 + 33487651 = 33487778
139 + 33487639 = 33487778
157 + 33487621 = 33487778
199 + 33487579 = 33487778

Showing the first eight; more decompositions exist.
