Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620250, here are decompositions:
- 41 + 31620209 = 31620250
- 47 + 31620203 = 31620250
- 59 + 31620191 = 31620250
- 83 + 31620167 = 31620250
- 191 + 31620059 = 31620250
- 257 + 31619993 = 31620250
- 269 + 31619981 = 31620250
- 401 + 31619849 = 31620250
Showing the first eight; more decompositions exist.
