Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40736, here are decompositions:

37 + 40699 = 40736
43 + 40693 = 40736
97 + 40639 = 40736
109 + 40627 = 40736
127 + 40609 = 40736
139 + 40597 = 40736
193 + 40543 = 40736
229 + 40507 = 40736

Showing the first eight; more decompositions exist.
