Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71684, here are decompositions:
- 13 + 71671 = 71684
- 37 + 71647 = 71684
- 157 + 71527 = 71684
- 181 + 71503 = 71684
- 211 + 71473 = 71684
- 241 + 71443 = 71684
- 271 + 71413 = 71684
- 331 + 71353 = 71684
Showing the first eight; more decompositions exist.
