Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425508, here are decompositions:
- 61 + 2147425447 = 2147425508
- 97 + 2147425411 = 2147425508
- 127 + 2147425381 = 2147425508
- 199 + 2147425309 = 2147425508
- 211 + 2147425297 = 2147425508
- 271 + 2147425237 = 2147425508
- 691 + 2147424817 = 2147425508
- 919 + 2147424589 = 2147425508
Showing the first eight; more decompositions exist.
