Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580780, here are decompositions:

3 + 33580777 = 33580780
11 + 33580769 = 33580780
53 + 33580727 = 33580780
71 + 33580709 = 33580780
137 + 33580643 = 33580780
227 + 33580553 = 33580780
239 + 33580541 = 33580780
257 + 33580523 = 33580780

Showing the first eight; more decompositions exist.
