Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003240, here are decompositions:

41 + 1003199 = 1003240
47 + 1003193 = 1003240
107 + 1003133 = 1003240
131 + 1003109 = 1003240
137 + 1003103 = 1003240
149 + 1003091 = 1003240
191 + 1003049 = 1003240
239 + 1003001 = 1003240

Showing the first eight; more decompositions exist.
