Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71888, here are decompositions:
- 7 + 71881 = 71888
- 67 + 71821 = 71888
- 79 + 71809 = 71888
- 127 + 71761 = 71888
- 181 + 71707 = 71888
- 241 + 71647 = 71888
- 337 + 71551 = 71888
- 409 + 71479 = 71888
Showing the first eight; more decompositions exist.
