Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47442, here are decompositions:
- 11 + 47431 = 47442
- 23 + 47419 = 47442
- 53 + 47389 = 47442
- 61 + 47381 = 47442
- 79 + 47363 = 47442
- 89 + 47353 = 47442
- 103 + 47339 = 47442
- 139 + 47303 = 47442
Showing the first eight; more decompositions exist.
