Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87426, here are decompositions:
- 5 + 87421 = 87426
- 19 + 87407 = 87426
- 23 + 87403 = 87426
- 43 + 87383 = 87426
- 67 + 87359 = 87426
- 89 + 87337 = 87426
- 103 + 87323 = 87426
- 109 + 87317 = 87426
Showing the first eight; more decompositions exist.
