Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64620, here are decompositions:
- 7 + 64613 = 64620
- 11 + 64609 = 64620
- 19 + 64601 = 64620
- 29 + 64591 = 64620
- 41 + 64579 = 64620
- 43 + 64577 = 64620
- 53 + 64567 = 64620
- 67 + 64553 = 64620
Showing the first eight; more decompositions exist.
