Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507072, here are decompositions:

13 + 33507059 = 33507072
43 + 33507029 = 33507072
251 + 33506821 = 33507072
271 + 33506801 = 33507072
331 + 33506741 = 33507072
383 + 33506689 = 33507072
409 + 33506663 = 33507072
449 + 33506623 = 33507072

Showing the first eight; more decompositions exist.
