Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87432, here are decompositions:
- 5 + 87427 = 87432
- 11 + 87421 = 87432
- 29 + 87403 = 87432
- 73 + 87359 = 87432
- 109 + 87323 = 87432
- 139 + 87293 = 87432
- 151 + 87281 = 87432
- 179 + 87253 = 87432
Showing the first eight; more decompositions exist.
