Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753478, here are decompositions:

17 + 8753461 = 8753478
29 + 8753449 = 8753478
37 + 8753441 = 8753478
109 + 8753369 = 8753478
211 + 8753267 = 8753478
271 + 8753207 = 8753478
281 + 8753197 = 8753478
317 + 8753161 = 8753478

Showing the first eight; more decompositions exist.
