Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489916, here are decompositions:
- 7 + 2147489909 = 2147489916
- 17 + 2147489899 = 2147489916
- 43 + 2147489873 = 2147489916
- 67 + 2147489849 = 2147489916
- 73 + 2147489843 = 2147489916
- 97 + 2147489819 = 2147489916
- 199 + 2147489717 = 2147489916
- 263 + 2147489653 = 2147489916
Showing the first eight; more decompositions exist.
