Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490890, here are decompositions:

47 + 33490843 = 33490890
73 + 33490817 = 33490890
89 + 33490801 = 33490890
109 + 33490781 = 33490890
113 + 33490777 = 33490890
127 + 33490763 = 33490890
197 + 33490693 = 33490890
263 + 33490627 = 33490890

Showing the first eight; more decompositions exist.
