Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494990, here are decompositions:

157 + 33494833 = 33494990
229 + 33494761 = 33494990
241 + 33494749 = 33494990
307 + 33494683 = 33494990
313 + 33494677 = 33494990
379 + 33494611 = 33494990
433 + 33494557 = 33494990
457 + 33494533 = 33494990

Showing the first eight; more decompositions exist.
