Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618280, here are decompositions:

29 + 33618251 = 33618280
71 + 33618209 = 33618280
89 + 33618191 = 33618280
107 + 33618173 = 33618280
131 + 33618149 = 33618280
251 + 33618029 = 33618280
281 + 33617999 = 33618280
317 + 33617963 = 33618280

Showing the first eight; more decompositions exist.
