Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487804, here are decompositions:

47 + 33487757 = 33487804
71 + 33487733 = 33487804
173 + 33487631 = 33487804
197 + 33487607 = 33487804
293 + 33487511 = 33487804
353 + 33487451 = 33487804
461 + 33487343 = 33487804
491 + 33487313 = 33487804

Showing the first eight; more decompositions exist.
