Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543144, here are decompositions:

73 + 33543071 = 33543144
83 + 33543061 = 33543144
113 + 33543031 = 33543144
127 + 33543017 = 33543144
157 + 33542987 = 33543144
163 + 33542981 = 33543144
181 + 33542963 = 33543144
191 + 33542953 = 33543144

Showing the first eight; more decompositions exist.
