Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423864, here are decompositions:
- 13 + 2147423851 = 2147423864
- 43 + 2147423821 = 2147423864
- 151 + 2147423713 = 2147423864
- 163 + 2147423701 = 2147423864
- 181 + 2147423683 = 2147423864
- 193 + 2147423671 = 2147423864
- 277 + 2147423587 = 2147423864
- 307 + 2147423557 = 2147423864
Showing the first eight; more decompositions exist.
