Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478330, here are decompositions:

59 + 478271 = 478330
71 + 478259 = 478330
89 + 478241 = 478330
131 + 478199 = 478330
173 + 478157 = 478330
191 + 478139 = 478330
263 + 478067 = 478330
353 + 477977 = 478330

Showing the first eight; more decompositions exist.
