Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71900, here are decompositions:
- 13 + 71887 = 71900
- 19 + 71881 = 71900
- 79 + 71821 = 71900
- 139 + 71761 = 71900
- 181 + 71719 = 71900
- 193 + 71707 = 71900
- 229 + 71671 = 71900
- 307 + 71593 = 71900
Showing the first eight; more decompositions exist.
