Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425442, here are decompositions:
- 31 + 2147425411 = 2147425442
- 61 + 2147425381 = 2147425442
- 109 + 2147425333 = 2147425442
- 193 + 2147425249 = 2147425442
- 199 + 2147425243 = 2147425442
- 229 + 2147425213 = 2147425442
- 733 + 2147424709 = 2147425442
- 853 + 2147424589 = 2147425442
Showing the first eight; more decompositions exist.
