Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507142, here are decompositions:

5 + 33507137 = 33507142
83 + 33507059 = 33507142
113 + 33507029 = 33507142
239 + 33506903 = 33507142
401 + 33506741 = 33507142
479 + 33506663 = 33507142
563 + 33506579 = 33507142
569 + 33506573 = 33507142

Showing the first eight; more decompositions exist.
