Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487942, here are decompositions:

29 + 33487913 = 33487942
41 + 33487901 = 33487942
83 + 33487859 = 33487942
311 + 33487631 = 33487942
431 + 33487511 = 33487942
491 + 33487451 = 33487942
599 + 33487343 = 33487942
641 + 33487301 = 33487942

Showing the first eight; more decompositions exist.
