Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422108, here are decompositions:
- 11 + 2147422097 = 2147422108
- 47 + 2147422061 = 2147422108
- 71 + 2147422037 = 2147422108
- 89 + 2147422019 = 2147422108
- 197 + 2147421911 = 2147422108
- 647 + 2147421461 = 2147422108
- 659 + 2147421449 = 2147422108
- 929 + 2147421179 = 2147422108
Showing the first eight; more decompositions exist.
