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.
