Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 44128, here are decompositions:
- 5 + 44123 = 44128
- 17 + 44111 = 44128
- 41 + 44087 = 44128
- 101 + 44027 = 44128
- 107 + 44021 = 44128
- 131 + 43997 = 44128
- 137 + 43991 = 44128
- 167 + 43961 = 44128
Showing the first eight; more decompositions exist.
