Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478556, here are decompositions:

73 + 478483 = 478556
97 + 478459 = 478556
103 + 478453 = 478556
139 + 478417 = 478556
157 + 478399 = 478556
283 + 478273 = 478556
313 + 478243 = 478556
349 + 478207 = 478556

Showing the first eight; more decompositions exist.
