Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615740, here are decompositions:

3 + 33615737 = 33615740
73 + 33615667 = 33615740
79 + 33615661 = 33615740
97 + 33615643 = 33615740
139 + 33615601 = 33615740
157 + 33615583 = 33615740
661 + 33615079 = 33615740
733 + 33615007 = 33615740

Showing the first eight; more decompositions exist.
