Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42456, here are decompositions:
- 5 + 42451 = 42456
- 13 + 42443 = 42456
- 19 + 42437 = 42456
- 23 + 42433 = 42456
- 47 + 42409 = 42456
- 53 + 42403 = 42456
- 59 + 42397 = 42456
- 83 + 42373 = 42456
Showing the first eight; more decompositions exist.
