Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530444, here are decompositions:
- 7 + 31530437 = 31530444
- 53 + 31530391 = 31530444
- 61 + 31530383 = 31530444
- 67 + 31530377 = 31530444
- 97 + 31530347 = 31530444
- 103 + 31530341 = 31530444
- 151 + 31530293 = 31530444
- 233 + 31530211 = 31530444
Showing the first eight; more decompositions exist.
