Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422390, here are decompositions:
- 17 + 2147422373 = 2147422390
- 59 + 2147422331 = 2147422390
- 149 + 2147422241 = 2147422390
- 251 + 2147422139 = 2147422390
- 263 + 2147422127 = 2147422390
- 293 + 2147422097 = 2147422390
- 353 + 2147422037 = 2147422390
- 401 + 2147421989 = 2147422390
Showing the first eight; more decompositions exist.
