Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531140, here are decompositions:

43 + 33531097 = 33531140
79 + 33531061 = 33531140
109 + 33531031 = 33531140
163 + 33530977 = 33531140
241 + 33530899 = 33531140
283 + 33530857 = 33531140
367 + 33530773 = 33531140
439 + 33530701 = 33531140

Showing the first eight; more decompositions exist.
