Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86242, here are decompositions:
- 3 + 86239 = 86242
- 41 + 86201 = 86242
- 59 + 86183 = 86242
- 71 + 86171 = 86242
- 131 + 86111 = 86242
- 173 + 86069 = 86242
- 251 + 85991 = 86242
- 311 + 85931 = 86242
Showing the first eight; more decompositions exist.
