Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478632, here are decompositions:
- 149 + 31478483 = 31478632
- 233 + 31478399 = 31478632
- 239 + 31478393 = 31478632
- 281 + 31478351 = 31478632
- 443 + 31478189 = 31478632
- 461 + 31478171 = 31478632
- 503 + 31478129 = 31478632
- 641 + 31477991 = 31478632
Showing the first eight; more decompositions exist.
