Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422078, here are decompositions:
- 17 + 2147422061 = 2147422078
- 41 + 2147422037 = 2147422078
- 59 + 2147422019 = 2147422078
- 89 + 2147421989 = 2147422078
- 167 + 2147421911 = 2147422078
- 617 + 2147421461 = 2147422078
- 911 + 2147421167 = 2147422078
- 929 + 2147421149 = 2147422078
Showing the first eight; more decompositions exist.
