Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563248, here are decompositions:
- 61 + 31563187 = 31563248
- 331 + 31562917 = 31563248
- 337 + 31562911 = 31563248
- 421 + 31562827 = 31563248
- 571 + 31562677 = 31563248
- 631 + 31562617 = 31563248
- 859 + 31562389 = 31563248
- 919 + 31562329 = 31563248
Showing the first eight; more decompositions exist.
