Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509742, here are decompositions:

29 + 33509713 = 33509742
59 + 33509683 = 33509742
61 + 33509681 = 33509742
83 + 33509659 = 33509742
109 + 33509633 = 33509742
139 + 33509603 = 33509742
173 + 33509569 = 33509742
181 + 33509561 = 33509742

Showing the first eight; more decompositions exist.
