Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64900, here are decompositions:
- 23 + 64877 = 64900
- 29 + 64871 = 64900
- 47 + 64853 = 64900
- 83 + 64817 = 64900
- 89 + 64811 = 64900
- 107 + 64793 = 64900
- 137 + 64763 = 64900
- 191 + 64709 = 64900
Showing the first eight; more decompositions exist.
