Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78478, here are decompositions:

11 + 78467 = 78478
41 + 78437 = 78478
131 + 78347 = 78478
137 + 78341 = 78478
167 + 78311 = 78478
311 + 78167 = 78478
419 + 78059 = 78478
461 + 78017 = 78478

Showing the first eight; more decompositions exist.
