Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87398, here are decompositions:
- 61 + 87337 = 87398
- 211 + 87187 = 87398
- 277 + 87121 = 87398
- 349 + 87049 = 87398
- 439 + 86959 = 87398
- 541 + 86857 = 87398
- 547 + 86851 = 87398
- 631 + 86767 = 87398
Showing the first eight; more decompositions exist.
