Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71860, here are decompositions:
- 11 + 71849 = 71860
- 17 + 71843 = 71860
- 23 + 71837 = 71860
- 53 + 71807 = 71860
- 71 + 71789 = 71860
- 83 + 71777 = 71860
- 149 + 71711 = 71860
- 167 + 71693 = 71860
Showing the first eight; more decompositions exist.
