Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28774, here are decompositions:
- 3 + 28771 = 28774
- 23 + 28751 = 28774
- 71 + 28703 = 28774
- 113 + 28661 = 28774
- 131 + 28643 = 28774
- 167 + 28607 = 28774
- 227 + 28547 = 28774
- 233 + 28541 = 28774
Showing the first eight; more decompositions exist.
