Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487072, here are decompositions:
- 23 + 487049 = 487072
- 59 + 487013 = 487072
- 101 + 486971 = 487072
- 149 + 486923 = 487072
- 233 + 486839 = 487072
- 239 + 486833 = 487072
- 251 + 486821 = 487072
- 359 + 486713 = 487072
Showing the first eight; more decompositions exist.
