Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75478, here are decompositions:

41 + 75437 = 75478
47 + 75431 = 75478
71 + 75407 = 75478
89 + 75389 = 75478
101 + 75377 = 75478
131 + 75347 = 75478
149 + 75329 = 75478
239 + 75239 = 75478

Showing the first eight; more decompositions exist.
