Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023186, here are decompositions:

13 + 1023173 = 1023186
19 + 1023167 = 1023186
23 + 1023163 = 1023186
53 + 1023133 = 1023186
79 + 1023107 = 1023186
103 + 1023083 = 1023186
107 + 1023079 = 1023186
139 + 1023047 = 1023186

Showing the first eight; more decompositions exist.
