Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023990, here are decompositions:

13 + 1023977 = 1023990
17 + 1023973 = 1023990
41 + 1023949 = 1023990
43 + 1023947 = 1023990
47 + 1023943 = 1023990
139 + 1023851 = 1023990
151 + 1023839 = 1023990
157 + 1023833 = 1023990

Showing the first eight; more decompositions exist.
