Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531100, here are decompositions:

3 + 33531097 = 33531100
17 + 33531083 = 33531100
23 + 33531077 = 33531100
41 + 33531059 = 33531100
89 + 33531011 = 33531100
101 + 33530999 = 33531100
131 + 33530969 = 33531100
263 + 33530837 = 33531100

Showing the first eight; more decompositions exist.
