Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21232, here are decompositions:
- 5 + 21227 = 21232
- 11 + 21221 = 21232
- 41 + 21191 = 21232
- 53 + 21179 = 21232
- 83 + 21149 = 21232
- 89 + 21143 = 21232
- 131 + 21101 = 21232
- 173 + 21059 = 21232
Showing the first eight; more decompositions exist.
