Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423784, here are decompositions:
- 13 + 2147423771 = 2147423784
- 31 + 2147423753 = 2147423784
- 41 + 2147423743 = 2147423784
- 67 + 2147423717 = 2147423784
- 71 + 2147423713 = 2147423784
- 73 + 2147423711 = 2147423784
- 83 + 2147423701 = 2147423784
- 101 + 2147423683 = 2147423784
Showing the first eight; more decompositions exist.
