Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71750, here are decompositions:
- 31 + 71719 = 71750
- 37 + 71713 = 71750
- 43 + 71707 = 71750
- 79 + 71671 = 71750
- 103 + 71647 = 71750
- 157 + 71593 = 71750
- 181 + 71569 = 71750
- 199 + 71551 = 71750
Showing the first eight; more decompositions exist.
