Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023178, here are decompositions:

5 + 1023173 = 1023178
11 + 1023167 = 1023178
71 + 1023107 = 1023178
131 + 1023047 = 1023178
137 + 1023041 = 1023178
197 + 1022981 = 1023178
449 + 1022729 = 1023178
587 + 1022591 = 1023178

Showing the first eight; more decompositions exist.
