Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002378, here are decompositions:

17 + 1002361 = 1002378
19 + 1002359 = 1002378
29 + 1002349 = 1002378
31 + 1002347 = 1002378
37 + 1002341 = 1002378
79 + 1002299 = 1002378
89 + 1002289 = 1002378
131 + 1002247 = 1002378

Showing the first eight; more decompositions exist.
