Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74578, here are decompositions:

5 + 74573 = 74578
11 + 74567 = 74578
17 + 74561 = 74578
47 + 74531 = 74578
71 + 74507 = 74578
89 + 74489 = 74578
107 + 74471 = 74578
137 + 74441 = 74578

Showing the first eight; more decompositions exist.
