Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71786, here are decompositions:
- 67 + 71719 = 71786
- 73 + 71713 = 71786
- 79 + 71707 = 71786
- 139 + 71647 = 71786
- 193 + 71593 = 71786
- 223 + 71563 = 71786
- 283 + 71503 = 71786
- 307 + 71479 = 71786
Showing the first eight; more decompositions exist.
