Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71222, here are decompositions:
- 13 + 71209 = 71222
- 31 + 71191 = 71222
- 61 + 71161 = 71222
- 79 + 71143 = 71222
- 103 + 71119 = 71222
- 163 + 71059 = 71222
- 199 + 71023 = 71222
- 211 + 71011 = 71222
Showing the first eight; more decompositions exist.
