Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87456, here are decompositions:
- 13 + 87443 = 87456
- 23 + 87433 = 87456
- 29 + 87427 = 87456
- 53 + 87403 = 87456
- 73 + 87383 = 87456
- 97 + 87359 = 87456
- 139 + 87317 = 87456
- 157 + 87299 = 87456
Showing the first eight; more decompositions exist.
