Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427442, here are decompositions:
- 233 + 2147427209 = 2147427442
- 269 + 2147427173 = 2147427442
- 359 + 2147427083 = 2147427442
- 401 + 2147427041 = 2147427442
- 491 + 2147426951 = 2147427442
- 599 + 2147426843 = 2147427442
- 761 + 2147426681 = 2147427442
- 773 + 2147426669 = 2147427442
Showing the first eight; more decompositions exist.
