Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64838, here are decompositions:
- 211 + 64627 = 64838
- 229 + 64609 = 64838
- 271 + 64567 = 64838
- 349 + 64489 = 64838
- 439 + 64399 = 64838
- 457 + 64381 = 64838
- 601 + 64237 = 64838
- 607 + 64231 = 64838
Showing the first eight; more decompositions exist.
