Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426732, here are decompositions:
- 103 + 2147426629 = 2147426732
- 109 + 2147426623 = 2147426732
- 181 + 2147426551 = 2147426732
- 211 + 2147426521 = 2147426732
- 313 + 2147426419 = 2147426732
- 331 + 2147426401 = 2147426732
- 379 + 2147426353 = 2147426732
- 571 + 2147426161 = 2147426732
Showing the first eight; more decompositions exist.
