Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007478, here are decompositions:

11 + 1007467 = 1007478
19 + 1007459 = 1007478
37 + 1007441 = 1007478
61 + 1007417 = 1007478
97 + 1007381 = 1007478
139 + 1007339 = 1007478
179 + 1007299 = 1007478
181 + 1007297 = 1007478

Showing the first eight; more decompositions exist.
