Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426588, here are decompositions:
- 31 + 2147426557 = 2147426588
- 37 + 2147426551 = 2147426588
- 61 + 2147426527 = 2147426588
- 67 + 2147426521 = 2147426588
- 211 + 2147426377 = 2147426588
- 271 + 2147426317 = 2147426588
- 367 + 2147426221 = 2147426588
- 421 + 2147426167 = 2147426588
Showing the first eight; more decompositions exist.
