Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487648, here are decompositions:

17 + 33487631 = 33487648
41 + 33487607 = 33487648
137 + 33487511 = 33487648
197 + 33487451 = 33487648
347 + 33487301 = 33487648
401 + 33487247 = 33487648
461 + 33487187 = 33487648
587 + 33487061 = 33487648

Showing the first eight; more decompositions exist.
