Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16442, here are decompositions:
- 31 + 16411 = 16442
- 61 + 16381 = 16442
- 73 + 16369 = 16442
- 79 + 16363 = 16442
- 103 + 16339 = 16442
- 109 + 16333 = 16442
- 193 + 16249 = 16442
- 211 + 16231 = 16442
Showing the first eight; more decompositions exist.
