Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42924, here are decompositions:
- 23 + 42901 = 42924
- 61 + 42863 = 42924
- 71 + 42853 = 42924
- 83 + 42841 = 42924
- 103 + 42821 = 42924
- 127 + 42797 = 42924
- 131 + 42793 = 42924
- 137 + 42787 = 42924
Showing the first eight; more decompositions exist.
