Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9042, here are decompositions:
- 13 + 9029 = 9042
- 29 + 9013 = 9042
- 31 + 9011 = 9042
- 41 + 9001 = 9042
- 43 + 8999 = 9042
- 71 + 8971 = 9042
- 73 + 8969 = 9042
- 79 + 8963 = 9042
Showing the first eight; more decompositions exist.
