Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494142, here are decompositions:

43 + 33494099 = 33494142
83 + 33494059 = 33494142
173 + 33493969 = 33494142
179 + 33493963 = 33494142
229 + 33493913 = 33494142
251 + 33493891 = 33494142
271 + 33493871 = 33494142
313 + 33493829 = 33494142

Showing the first eight; more decompositions exist.
