Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547826, here are decompositions:
- 43 + 31547783 = 31547826
- 197 + 31547629 = 31547826
- 269 + 31547557 = 31547826
- 307 + 31547519 = 31547826
- 337 + 31547489 = 31547826
- 347 + 31547479 = 31547826
- 367 + 31547459 = 31547826
- 487 + 31547339 = 31547826
Showing the first eight; more decompositions exist.
