Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487518, here are decompositions:

5 + 33487513 = 33487518
7 + 33487511 = 33487518
11 + 33487507 = 33487518
41 + 33487477 = 33487518
67 + 33487451 = 33487518
101 + 33487417 = 33487518
131 + 33487387 = 33487518
199 + 33487319 = 33487518

Showing the first eight; more decompositions exist.
