Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153944, here are decompositions:
- 3 + 153941 = 153944
- 31 + 153913 = 153944
- 67 + 153877 = 153944
- 73 + 153871 = 153944
- 103 + 153841 = 153944
- 127 + 153817 = 153944
- 181 + 153763 = 153944
- 211 + 153733 = 153944
Showing the first eight; more decompositions exist.
