Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611920, here are decompositions:

107 + 33611813 = 33611920
113 + 33611807 = 33611920
197 + 33611723 = 33611920
317 + 33611603 = 33611920
347 + 33611573 = 33611920
359 + 33611561 = 33611920
383 + 33611537 = 33611920
431 + 33611489 = 33611920

Showing the first eight; more decompositions exist.
