Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422886, here are decompositions:
- 13 + 2147422873 = 2147422886
- 67 + 2147422819 = 2147422886
- 97 + 2147422789 = 2147422886
- 109 + 2147422777 = 2147422886
- 139 + 2147422747 = 2147422886
- 163 + 2147422723 = 2147422886
- 223 + 2147422663 = 2147422886
- 229 + 2147422657 = 2147422886
Showing the first eight; more decompositions exist.
