Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002578, here are decompositions:

61 + 1002517 = 1002578
67 + 1002511 = 1002578
97 + 1002481 = 1002578
127 + 1002451 = 1002578
151 + 1002427 = 1002578
229 + 1002349 = 1002578
331 + 1002247 = 1002578
337 + 1002241 = 1002578

Showing the first eight; more decompositions exist.
