Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487418, here are decompositions:

31 + 33487387 = 33487418
109 + 33487309 = 33487418
157 + 33487261 = 33487418
199 + 33487219 = 33487418
229 + 33487189 = 33487418
271 + 33487147 = 33487418
337 + 33487081 = 33487418
397 + 33487021 = 33487418

Showing the first eight; more decompositions exist.
