Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42746, here are decompositions:
- 3 + 42743 = 42746
- 19 + 42727 = 42746
- 37 + 42709 = 42746
- 43 + 42703 = 42746
- 79 + 42667 = 42746
- 97 + 42649 = 42746
- 103 + 42643 = 42746
- 157 + 42589 = 42746
Showing the first eight; more decompositions exist.
