Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64670, here are decompositions:
- 3 + 64667 = 64670
- 7 + 64663 = 64670
- 37 + 64633 = 64670
- 43 + 64627 = 64670
- 61 + 64609 = 64670
- 79 + 64591 = 64670
- 103 + 64567 = 64670
- 157 + 64513 = 64670
Showing the first eight; more decompositions exist.
