Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71830, here are decompositions:
- 23 + 71807 = 71830
- 41 + 71789 = 71830
- 53 + 71777 = 71830
- 89 + 71741 = 71830
- 131 + 71699 = 71830
- 137 + 71693 = 71830
- 167 + 71663 = 71830
- 197 + 71633 = 71830
Showing the first eight; more decompositions exist.
