Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19822, here are decompositions:
- 3 + 19819 = 19822
- 29 + 19793 = 19822
- 59 + 19763 = 19822
- 71 + 19751 = 19822
- 83 + 19739 = 19822
- 113 + 19709 = 19822
- 239 + 19583 = 19822
- 251 + 19571 = 19822
Showing the first eight; more decompositions exist.
