Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423876, here are decompositions:
- 163 + 2147423713 = 2147423876
- 193 + 2147423683 = 2147423876
- 229 + 2147423647 = 2147423876
- 313 + 2147423563 = 2147423876
- 607 + 2147423269 = 2147423876
- 733 + 2147423143 = 2147423876
- 739 + 2147423137 = 2147423876
- 1087 + 2147422789 = 2147423876
Showing the first eight; more decompositions exist.
