Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11478, here are decompositions:

7 + 11471 = 11478
11 + 11467 = 11478
31 + 11447 = 11478
41 + 11437 = 11478
67 + 11411 = 11478
79 + 11399 = 11478
109 + 11369 = 11478
127 + 11351 = 11478

Showing the first eight; more decompositions exist.
