Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003478, here are decompositions:

61 + 1003417 = 1003478
67 + 1003411 = 1003478
97 + 1003381 = 1003478
109 + 1003369 = 1003478
127 + 1003351 = 1003478
199 + 1003279 = 1003478
277 + 1003201 = 1003478
337 + 1003141 = 1003478

Showing the first eight; more decompositions exist.
