Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33599972, here are decompositions:

139 + 33599833 = 33599972
151 + 33599821 = 33599972
181 + 33599791 = 33599972
193 + 33599779 = 33599972
199 + 33599773 = 33599972
313 + 33599659 = 33599972
541 + 33599431 = 33599972
631 + 33599341 = 33599972

Showing the first eight; more decompositions exist.
