Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607890, here are decompositions:

31 + 33607859 = 33607890
47 + 33607843 = 33607890
59 + 33607831 = 33607890
73 + 33607817 = 33607890
89 + 33607801 = 33607890
137 + 33607753 = 33607890
157 + 33607733 = 33607890
163 + 33607727 = 33607890

Showing the first eight; more decompositions exist.
