Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30984, here are decompositions:
- 7 + 30977 = 30984
- 13 + 30971 = 30984
- 43 + 30941 = 30984
- 47 + 30937 = 30984
- 53 + 30931 = 30984
- 73 + 30911 = 30984
- 103 + 30881 = 30984
- 113 + 30871 = 30984
Showing the first eight; more decompositions exist.
