Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30944, here are decompositions:
- 3 + 30941 = 30944
- 7 + 30937 = 30944
- 13 + 30931 = 30944
- 73 + 30871 = 30944
- 103 + 30841 = 30944
- 127 + 30817 = 30944
- 163 + 30781 = 30944
- 181 + 30763 = 30944
Showing the first eight; more decompositions exist.
