Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670942, here are decompositions:
- 23 + 8670919 = 8670942
- 73 + 8670869 = 8670942
- 79 + 8670863 = 8670942
- 131 + 8670811 = 8670942
- 151 + 8670791 = 8670942
- 191 + 8670751 = 8670942
- 199 + 8670743 = 8670942
- 229 + 8670713 = 8670942
Showing the first eight; more decompositions exist.
