Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530430, here are decompositions:
- 11 + 31530419 = 31530430
- 47 + 31530383 = 31530430
- 53 + 31530377 = 31530430
- 83 + 31530347 = 31530430
- 89 + 31530341 = 31530430
- 137 + 31530293 = 31530430
- 227 + 31530203 = 31530430
- 233 + 31530197 = 31530430
Showing the first eight; more decompositions exist.
