Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507728, here are decompositions:

97 + 33507631 = 33507728
127 + 33507601 = 33507728
151 + 33507577 = 33507728
349 + 33507379 = 33507728
409 + 33507319 = 33507728
421 + 33507307 = 33507728
607 + 33507121 = 33507728
619 + 33507109 = 33507728

Showing the first eight; more decompositions exist.
