Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30636, here are decompositions:
- 5 + 30631 = 30636
- 43 + 30593 = 30636
- 59 + 30577 = 30636
- 79 + 30557 = 30636
- 83 + 30553 = 30636
- 97 + 30539 = 30636
- 107 + 30529 = 30636
- 127 + 30509 = 30636
Showing the first eight; more decompositions exist.
