Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478572, here are decompositions:

41 + 478531 = 478572
79 + 478493 = 478572
89 + 478483 = 478572
113 + 478459 = 478572
131 + 478441 = 478572
139 + 478433 = 478572
151 + 478421 = 478572
173 + 478399 = 478572

Showing the first eight; more decompositions exist.
