Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627140, here are decompositions:

37 + 33627103 = 33627140
61 + 33627079 = 33627140
67 + 33627073 = 33627140
109 + 33627031 = 33627140
139 + 33627001 = 33627140
163 + 33626977 = 33627140
241 + 33626899 = 33627140
331 + 33626809 = 33627140

Showing the first eight; more decompositions exist.
