Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42056, here are decompositions:
- 13 + 42043 = 42056
- 37 + 42019 = 42056
- 43 + 42013 = 42056
- 73 + 41983 = 42056
- 97 + 41959 = 42056
- 103 + 41953 = 42056
- 109 + 41947 = 42056
- 163 + 41893 = 42056
Showing the first eight; more decompositions exist.
