Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540896, here are decompositions:
- 29 + 31540867 = 31540896
- 59 + 31540837 = 31540896
- 73 + 31540823 = 31540896
- 83 + 31540813 = 31540896
- 109 + 31540787 = 31540896
- 113 + 31540783 = 31540896
- 173 + 31540723 = 31540896
- 197 + 31540699 = 31540896
Showing the first eight; more decompositions exist.
