Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422276, here are decompositions:
- 5 + 2147422271 = 2147422276
- 47 + 2147422229 = 2147422276
- 137 + 2147422139 = 2147422276
- 149 + 2147422127 = 2147422276
- 179 + 2147422097 = 2147422276
- 239 + 2147422037 = 2147422276
- 257 + 2147422019 = 2147422276
- 383 + 2147421893 = 2147422276
Showing the first eight; more decompositions exist.
