Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604124, here are decompositions:
- 67 + 31604057 = 31604124
- 73 + 31604051 = 31604124
- 137 + 31603987 = 31604124
- 191 + 31603933 = 31604124
- 193 + 31603931 = 31604124
- 281 + 31603843 = 31604124
- 367 + 31603757 = 31604124
- 373 + 31603751 = 31604124
Showing the first eight; more decompositions exist.
