Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71742, here are decompositions:
- 23 + 71719 = 71742
- 29 + 71713 = 71742
- 31 + 71711 = 71742
- 43 + 71699 = 71742
- 71 + 71671 = 71742
- 79 + 71663 = 71742
- 109 + 71633 = 71742
- 149 + 71593 = 71742
Showing the first eight; more decompositions exist.
