Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620164, here are decompositions:
- 5 + 8620159 = 8620164
- 13 + 8620151 = 8620164
- 23 + 8620141 = 8620164
- 31 + 8620133 = 8620164
- 43 + 8620121 = 8620164
- 53 + 8620111 = 8620164
- 101 + 8620063 = 8620164
- 167 + 8619997 = 8620164
Showing the first eight; more decompositions exist.
