Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490042, here are decompositions:

11 + 33490031 = 33490042
101 + 33489941 = 33490042
251 + 33489791 = 33490042
353 + 33489689 = 33490042
359 + 33489683 = 33490042
389 + 33489653 = 33490042
419 + 33489623 = 33490042
431 + 33489611 = 33490042

Showing the first eight; more decompositions exist.
