Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87354, here are decompositions:
- 17 + 87337 = 87354
- 31 + 87323 = 87354
- 37 + 87317 = 87354
- 41 + 87313 = 87354
- 61 + 87293 = 87354
- 73 + 87281 = 87354
- 97 + 87257 = 87354
- 101 + 87253 = 87354
Showing the first eight; more decompositions exist.
