Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42758, here are decompositions:
- 7 + 42751 = 42758
- 31 + 42727 = 42758
- 61 + 42697 = 42758
- 109 + 42649 = 42758
- 181 + 42577 = 42758
- 271 + 42487 = 42758
- 307 + 42451 = 42758
- 349 + 42409 = 42758
Showing the first eight; more decompositions exist.
