Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16520, here are decompositions:
- 43 + 16477 = 16520
- 67 + 16453 = 16520
- 73 + 16447 = 16520
- 103 + 16417 = 16520
- 109 + 16411 = 16520
- 139 + 16381 = 16520
- 151 + 16369 = 16520
- 157 + 16363 = 16520
Showing the first eight; more decompositions exist.
