Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42884, here are decompositions:
- 31 + 42853 = 42884
- 43 + 42841 = 42884
- 97 + 42787 = 42884
- 157 + 42727 = 42884
- 181 + 42703 = 42884
- 241 + 42643 = 42884
- 307 + 42577 = 42884
- 313 + 42571 = 42884
Showing the first eight; more decompositions exist.
