Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42830, here are decompositions:
- 37 + 42793 = 42830
- 43 + 42787 = 42830
- 79 + 42751 = 42830
- 103 + 42727 = 42830
- 127 + 42703 = 42830
- 163 + 42667 = 42830
- 181 + 42649 = 42830
- 241 + 42589 = 42830
Showing the first eight; more decompositions exist.
