Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147529292, here are decompositions:
- 53 + 2147529239 = 2147529292
- 71 + 2147529221 = 2147529292
- 89 + 2147529203 = 2147529292
- 101 + 2147529191 = 2147529292
- 131 + 2147529161 = 2147529292
- 401 + 2147528891 = 2147529292
- 431 + 2147528861 = 2147529292
- 449 + 2147528843 = 2147529292
Showing the first eight; more decompositions exist.
