Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504128, here are decompositions:
- 31 + 31504097 = 31504128
- 41 + 31504087 = 31504128
- 151 + 31503977 = 31504128
- 157 + 31503971 = 31504128
- 167 + 31503961 = 31504128
- 197 + 31503931 = 31504128
- 199 + 31503929 = 31504128
- 211 + 31503917 = 31504128
Showing the first eight; more decompositions exist.
