Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42984, here are decompositions:
- 5 + 42979 = 42984
- 17 + 42967 = 42984
- 23 + 42961 = 42984
- 31 + 42953 = 42984
- 41 + 42943 = 42984
- 47 + 42937 = 42984
- 61 + 42923 = 42984
- 83 + 42901 = 42984
Showing the first eight; more decompositions exist.
