Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487618, here are decompositions:

11 + 33487607 = 33487618
107 + 33487511 = 33487618
167 + 33487451 = 33487618
317 + 33487301 = 33487618
347 + 33487271 = 33487618
431 + 33487187 = 33487618
467 + 33487151 = 33487618
557 + 33487061 = 33487618

Showing the first eight; more decompositions exist.
