Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738478, here are decompositions:

5 + 8738473 = 8738478
29 + 8738449 = 8738478
31 + 8738447 = 8738478
41 + 8738437 = 8738478
71 + 8738407 = 8738478
79 + 8738399 = 8738478
101 + 8738377 = 8738478
127 + 8738351 = 8738478

Showing the first eight; more decompositions exist.
