Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003228, here are decompositions:

29 + 1003199 = 1003228
131 + 1003097 = 1003228
137 + 1003091 = 1003228
179 + 1003049 = 1003228
227 + 1003001 = 1003228
311 + 1002917 = 1003228
419 + 1002809 = 1003228
431 + 1002797 = 1003228

Showing the first eight; more decompositions exist.
