Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86842, here are decompositions:
- 5 + 86837 = 86842
- 29 + 86813 = 86842
- 59 + 86783 = 86842
- 71 + 86771 = 86842
- 89 + 86753 = 86842
- 113 + 86729 = 86842
- 131 + 86711 = 86842
- 149 + 86693 = 86842
Showing the first eight; more decompositions exist.
