Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625160, here are decompositions:

73 + 33625087 = 33625160
193 + 33624967 = 33625160
229 + 33624931 = 33625160
277 + 33624883 = 33625160
397 + 33624763 = 33625160
463 + 33624697 = 33625160
577 + 33624583 = 33625160
619 + 33624541 = 33625160

Showing the first eight; more decompositions exist.
