Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493088, here are decompositions:
- 11 + 2147493077 = 2147493088
- 71 + 2147493017 = 2147493088
- 149 + 2147492939 = 2147493088
- 347 + 2147492741 = 2147493088
- 449 + 2147492639 = 2147493088
- 467 + 2147492621 = 2147493088
- 479 + 2147492609 = 2147493088
- 491 + 2147492597 = 2147493088
Showing the first eight; more decompositions exist.
