Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009478, here are decompositions:

61 + 1009417 = 1009478
79 + 1009399 = 1009478
109 + 1009369 = 1009478
157 + 1009321 = 1009478
241 + 1009237 = 1009478
271 + 1009207 = 1009478
277 + 1009201 = 1009478
487 + 1008991 = 1009478

Showing the first eight; more decompositions exist.
