Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40478, here are decompositions:

7 + 40471 = 40478
19 + 40459 = 40478
127 + 40351 = 40478
241 + 40237 = 40478
349 + 40129 = 40478
367 + 40111 = 40478
379 + 40099 = 40478
439 + 40039 = 40478

Showing the first eight; more decompositions exist.
