Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507380, here are decompositions:

3 + 33507377 = 33507380
61 + 33507319 = 33507380
73 + 33507307 = 33507380
157 + 33507223 = 33507380
271 + 33507109 = 33507380
433 + 33506947 = 33507380
523 + 33506857 = 33507380
607 + 33506773 = 33507380

Showing the first eight; more decompositions exist.
