Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487666, here are decompositions:

59 + 33487607 = 33487666
347 + 33487319 = 33487666
353 + 33487313 = 33487666
389 + 33487277 = 33487666
419 + 33487247 = 33487666
479 + 33487187 = 33487666
503 + 33487163 = 33487666
617 + 33487049 = 33487666

Showing the first eight; more decompositions exist.
