Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71854, here are decompositions:
- 5 + 71849 = 71854
- 11 + 71843 = 71854
- 17 + 71837 = 71854
- 47 + 71807 = 71854
- 113 + 71741 = 71854
- 191 + 71663 = 71854
- 257 + 71597 = 71854
- 317 + 71537 = 71854
Showing the first eight; more decompositions exist.
