Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618204, here are decompositions:
- 5 + 31618199 = 31618204
- 11 + 31618193 = 31618204
- 17 + 31618187 = 31618204
- 41 + 31618163 = 31618204
- 71 + 31618133 = 31618204
- 83 + 31618121 = 31618204
- 251 + 31617953 = 31618204
- 263 + 31617941 = 31618204
Showing the first eight; more decompositions exist.
