Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535432, here are decompositions:
- 3 + 31535429 = 31535432
- 13 + 31535419 = 31535432
- 199 + 31535233 = 31535432
- 349 + 31535083 = 31535432
- 373 + 31535059 = 31535432
- 421 + 31535011 = 31535432
- 433 + 31534999 = 31535432
- 601 + 31534831 = 31535432
Showing the first eight; more decompositions exist.
