Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16490, here are decompositions:
- 3 + 16487 = 16490
- 13 + 16477 = 16490
- 37 + 16453 = 16490
- 43 + 16447 = 16490
- 73 + 16417 = 16490
- 79 + 16411 = 16490
- 109 + 16381 = 16490
- 127 + 16363 = 16490
Showing the first eight; more decompositions exist.
