Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57042, here are decompositions:
- 5 + 57037 = 57042
- 43 + 56999 = 57042
- 53 + 56989 = 57042
- 59 + 56983 = 57042
- 79 + 56963 = 57042
- 101 + 56941 = 57042
- 113 + 56929 = 57042
- 131 + 56911 = 57042
Showing the first eight; more decompositions exist.
