Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620204, here are decompositions:
- 13 + 31620191 = 31620204
- 37 + 31620167 = 31620204
- 53 + 31620151 = 31620204
- 73 + 31620131 = 31620204
- 97 + 31620107 = 31620204
- 137 + 31620067 = 31620204
- 167 + 31620037 = 31620204
- 191 + 31620013 = 31620204
Showing the first eight; more decompositions exist.
