Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488240, here are decompositions:

73 + 33488167 = 33488240
103 + 33488137 = 33488240
109 + 33488131 = 33488240
139 + 33488101 = 33488240
193 + 33488047 = 33488240
199 + 33488041 = 33488240
241 + 33487999 = 33488240
271 + 33487969 = 33488240

Showing the first eight; more decompositions exist.
