Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023988, here are decompositions:

11 + 1023977 = 1023988
41 + 1023947 = 1023988
47 + 1023941 = 1023988
131 + 1023857 = 1023988
137 + 1023851 = 1023988
149 + 1023839 = 1023988
167 + 1023821 = 1023988
257 + 1023731 = 1023988

Showing the first eight; more decompositions exist.
