Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487978, here are decompositions:

5 + 33487973 = 33487978
71 + 33487907 = 33487978
101 + 33487877 = 33487978
131 + 33487847 = 33487978
347 + 33487631 = 33487978
467 + 33487511 = 33487978
659 + 33487319 = 33487978
677 + 33487301 = 33487978

Showing the first eight; more decompositions exist.
