Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71842, here are decompositions:
- 5 + 71837 = 71842
- 53 + 71789 = 71842
- 101 + 71741 = 71842
- 131 + 71711 = 71842
- 149 + 71693 = 71842
- 179 + 71663 = 71842
- 293 + 71549 = 71842
- 359 + 71483 = 71842
Showing the first eight; more decompositions exist.
