Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427488, here are decompositions:
- 61 + 2147427427 = 2147427488
- 331 + 2147427157 = 2147427488
- 337 + 2147427151 = 2147427488
- 397 + 2147427091 = 2147427488
- 487 + 2147427001 = 2147427488
- 499 + 2147426989 = 2147427488
- 859 + 2147426629 = 2147427488
- 937 + 2147426551 = 2147427488
Showing the first eight; more decompositions exist.
