Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487388, here are decompositions:

79 + 33487309 = 33487388
127 + 33487261 = 33487388
199 + 33487189 = 33487388
241 + 33487147 = 33487388
271 + 33487117 = 33487388
307 + 33487081 = 33487388
367 + 33487021 = 33487388
541 + 33486847 = 33487388

Showing the first eight; more decompositions exist.
