Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72830, here are decompositions:
- 7 + 72823 = 72830
- 13 + 72817 = 72830
- 67 + 72763 = 72830
- 97 + 72733 = 72830
- 103 + 72727 = 72830
- 151 + 72679 = 72830
- 157 + 72673 = 72830
- 181 + 72649 = 72830
Showing the first eight; more decompositions exist.
