Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426990, here are decompositions:
- 19 + 2147426971 = 2147426990
- 349 + 2147426641 = 2147426990
- 367 + 2147426623 = 2147426990
- 433 + 2147426557 = 2147426990
- 439 + 2147426551 = 2147426990
- 463 + 2147426527 = 2147426990
- 523 + 2147426467 = 2147426990
- 571 + 2147426419 = 2147426990
Showing the first eight; more decompositions exist.
