Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500390, here are decompositions:

61 + 33500329 = 33500390
67 + 33500323 = 33500390
73 + 33500317 = 33500390
127 + 33500263 = 33500390
181 + 33500209 = 33500390
283 + 33500107 = 33500390
307 + 33500083 = 33500390
379 + 33500011 = 33500390

Showing the first eight; more decompositions exist.
