Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012380, here are decompositions:

7 + 1012373 = 1012380
11 + 1012369 = 1012380
59 + 1012321 = 1012380
73 + 1012307 = 1012380
101 + 1012279 = 1012380
113 + 1012267 = 1012380
139 + 1012241 = 1012380
151 + 1012229 = 1012380

Showing the first eight; more decompositions exist.
