Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544546, here are decompositions:
- 3 + 31544543 = 31544546
- 13 + 31544533 = 31544546
- 37 + 31544509 = 31544546
- 199 + 31544347 = 31544546
- 223 + 31544323 = 31544546
- 367 + 31544179 = 31544546
- 379 + 31544167 = 31544546
- 457 + 31544089 = 31544546
Showing the first eight; more decompositions exist.
