Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592648, here are decompositions:
- 7 + 31592641 = 31592648
- 97 + 31592551 = 31592648
- 181 + 31592467 = 31592648
- 211 + 31592437 = 31592648
- 271 + 31592377 = 31592648
- 337 + 31592311 = 31592648
- 487 + 31592161 = 31592648
- 499 + 31592149 = 31592648
Showing the first eight; more decompositions exist.
