Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71486, here are decompositions:
- 3 + 71483 = 71486
- 7 + 71479 = 71486
- 13 + 71473 = 71486
- 43 + 71443 = 71486
- 67 + 71419 = 71486
- 73 + 71413 = 71486
- 97 + 71389 = 71486
- 127 + 71359 = 71486
Showing the first eight; more decompositions exist.
