Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42854, here are decompositions:
- 13 + 42841 = 42854
- 61 + 42793 = 42854
- 67 + 42787 = 42854
- 103 + 42751 = 42854
- 127 + 42727 = 42854
- 151 + 42703 = 42854
- 157 + 42697 = 42854
- 211 + 42643 = 42854
Showing the first eight; more decompositions exist.
