Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4478, here are decompositions:

31 + 4447 = 4478
37 + 4441 = 4478
139 + 4339 = 4478
151 + 4327 = 4478
181 + 4297 = 4478
277 + 4201 = 4478
349 + 4129 = 4478
367 + 4111 = 4478

Showing the first eight; more decompositions exist.
