Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491180, here are decompositions:

31 + 33491149 = 33491180
139 + 33491041 = 33491180
181 + 33490999 = 33491180
193 + 33490987 = 33491180
199 + 33490981 = 33491180
337 + 33490843 = 33491180
367 + 33490813 = 33491180
379 + 33490801 = 33491180

Showing the first eight; more decompositions exist.
