Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500142, here are decompositions:

31 + 33500111 = 33500142
41 + 33500101 = 33500142
59 + 33500083 = 33500142
103 + 33500039 = 33500142
131 + 33500011 = 33500142
173 + 33499969 = 33500142
199 + 33499943 = 33500142
233 + 33499909 = 33500142

Showing the first eight; more decompositions exist.
