Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42670, here are decompositions:
- 3 + 42667 = 42670
- 29 + 42641 = 42670
- 59 + 42611 = 42670
- 101 + 42569 = 42670
- 113 + 42557 = 42670
- 137 + 42533 = 42670
- 179 + 42491 = 42670
- 197 + 42473 = 42670
Showing the first eight; more decompositions exist.
