Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61830, here are decompositions:
- 11 + 61819 = 61830
- 17 + 61813 = 61830
- 73 + 61757 = 61830
- 79 + 61751 = 61830
- 101 + 61729 = 61830
- 107 + 61723 = 61830
- 113 + 61717 = 61830
- 127 + 61703 = 61830
Showing the first eight; more decompositions exist.
