Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531158, here are decompositions:

61 + 33531097 = 33531158
97 + 33531061 = 33531158
109 + 33531049 = 33531158
127 + 33531031 = 33531158
139 + 33531019 = 33531158
181 + 33530977 = 33531158
457 + 33530701 = 33531158
541 + 33530617 = 33531158

Showing the first eight; more decompositions exist.
