Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553778, here are decompositions:

7 + 33553771 = 33553778
19 + 33553759 = 33553778
31 + 33553747 = 33553778
127 + 33553651 = 33553778
229 + 33553549 = 33553778
241 + 33553537 = 33553778
409 + 33553369 = 33553778
421 + 33553357 = 33553778

Showing the first eight; more decompositions exist.
