Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7478, here are decompositions:

19 + 7459 = 7478
61 + 7417 = 7478
67 + 7411 = 7478
109 + 7369 = 7478
127 + 7351 = 7478
157 + 7321 = 7478
181 + 7297 = 7478
241 + 7237 = 7478

Showing the first eight; more decompositions exist.
