Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490686, here are decompositions:

59 + 33490627 = 33490686
79 + 33490607 = 33490686
83 + 33490603 = 33490686
107 + 33490579 = 33490686
113 + 33490573 = 33490686
139 + 33490547 = 33490686
149 + 33490537 = 33490686
157 + 33490529 = 33490686

Showing the first eight; more decompositions exist.
