Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87464, here are decompositions:
- 31 + 87433 = 87464
- 37 + 87427 = 87464
- 43 + 87421 = 87464
- 61 + 87403 = 87464
- 127 + 87337 = 87464
- 151 + 87313 = 87464
- 211 + 87253 = 87464
- 241 + 87223 = 87464
Showing the first eight; more decompositions exist.
