Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740478, here are decompositions:

31 + 8740447 = 8740478
67 + 8740411 = 8740478
151 + 8740327 = 8740478
157 + 8740321 = 8740478
349 + 8740129 = 8740478
367 + 8740111 = 8740478
541 + 8739937 = 8740478
577 + 8739901 = 8740478

Showing the first eight; more decompositions exist.
