Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16478, here are decompositions:
- 31 + 16447 = 16478
- 61 + 16417 = 16478
- 67 + 16411 = 16478
- 97 + 16381 = 16478
- 109 + 16369 = 16478
- 139 + 16339 = 16478
- 211 + 16267 = 16478
- 229 + 16249 = 16478
Showing the first eight; more decompositions exist.
