Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023388, here are decompositions:

59 + 1023329 = 1023388
71 + 1023317 = 1023388
89 + 1023299 = 1023388
131 + 1023257 = 1023388
167 + 1023221 = 1023388
281 + 1023107 = 1023388
347 + 1023041 = 1023388
659 + 1022729 = 1023388

Showing the first eight; more decompositions exist.
