Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74830, here are decompositions:

3 + 74827 = 74830
59 + 74771 = 74830
71 + 74759 = 74830
83 + 74747 = 74830
101 + 74729 = 74830
113 + 74717 = 74830
131 + 74699 = 74830
233 + 74597 = 74830

Showing the first eight; more decompositions exist.
