Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86442, here are decompositions:
- 19 + 86423 = 86442
- 29 + 86413 = 86442
- 43 + 86399 = 86442
- 53 + 86389 = 86442
- 61 + 86381 = 86442
- 71 + 86371 = 86442
- 73 + 86369 = 86442
- 89 + 86353 = 86442
Showing the first eight; more decompositions exist.
