Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618234, here are decompositions:
- 3 + 31618231 = 31618234
- 23 + 31618211 = 31618234
- 41 + 31618193 = 31618234
- 47 + 31618187 = 31618234
- 71 + 31618163 = 31618234
- 101 + 31618133 = 31618234
- 107 + 31618127 = 31618234
- 113 + 31618121 = 31618234
Showing the first eight; more decompositions exist.
