Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426742, here are decompositions:
- 61 + 2147426681 = 2147426742
- 73 + 2147426669 = 2147426742
- 101 + 2147426641 = 2147426742
- 113 + 2147426629 = 2147426742
- 191 + 2147426551 = 2147426742
- 199 + 2147426543 = 2147426742
- 271 + 2147426471 = 2147426742
- 283 + 2147426459 = 2147426742
Showing the first eight; more decompositions exist.
