Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64700, here are decompositions:
- 7 + 64693 = 64700
- 37 + 64663 = 64700
- 67 + 64633 = 64700
- 73 + 64627 = 64700
- 79 + 64621 = 64700
- 109 + 64591 = 64700
- 211 + 64489 = 64700
- 367 + 64333 = 64700
Showing the first eight; more decompositions exist.
