Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013788, here are decompositions:

47 + 1013741 = 1013788
59 + 1013729 = 1013788
71 + 1013717 = 1013788
89 + 1013699 = 1013788
101 + 1013687 = 1013788
107 + 1013681 = 1013788
179 + 1013609 = 1013788
257 + 1013531 = 1013788

Showing the first eight; more decompositions exist.
