Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147421092, here are decompositions:
- 43 + 2147421049 = 2147421092
- 73 + 2147421019 = 2147421092
- 373 + 2147420719 = 2147421092
- 409 + 2147420683 = 2147421092
- 499 + 2147420593 = 2147421092
- 673 + 2147420419 = 2147421092
- 823 + 2147420269 = 2147421092
- 1201 + 2147419891 = 2147421092
Showing the first eight; more decompositions exist.
