Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045380, here are decompositions:

13 + 1045367 = 1045380
31 + 1045349 = 1045380
59 + 1045321 = 1045380
71 + 1045309 = 1045380
73 + 1045307 = 1045380
103 + 1045277 = 1045380
107 + 1045273 = 1045380
139 + 1045241 = 1045380

Showing the first eight; more decompositions exist.
