Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507420, here are decompositions:

7 + 33507413 = 33507420
13 + 33507407 = 33507420
19 + 33507401 = 33507420
41 + 33507379 = 33507420
43 + 33507377 = 33507420
61 + 33507359 = 33507420
73 + 33507347 = 33507420
101 + 33507319 = 33507420

Showing the first eight; more decompositions exist.
