Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544492, here are decompositions:
- 181 + 31544311 = 31544492
- 211 + 31544281 = 31544492
- 271 + 31544221 = 31544492
- 313 + 31544179 = 31544492
- 439 + 31544053 = 31544492
- 619 + 31543873 = 31544492
- 709 + 31543783 = 31544492
- 769 + 31543723 = 31544492
Showing the first eight; more decompositions exist.
