Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487840, here are decompositions:

83 + 33487757 = 33487840
107 + 33487733 = 33487840
233 + 33487607 = 33487840
389 + 33487451 = 33487840
521 + 33487319 = 33487840
563 + 33487277 = 33487840
569 + 33487271 = 33487840
593 + 33487247 = 33487840

Showing the first eight; more decompositions exist.
