Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507280, here are decompositions:

113 + 33507167 = 33507280
173 + 33507107 = 33507280
251 + 33507029 = 33507280
383 + 33506897 = 33507280
461 + 33506819 = 33507280
479 + 33506801 = 33507280
503 + 33506777 = 33507280
617 + 33506663 = 33507280

Showing the first eight; more decompositions exist.
