Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498090, here are decompositions:
- 3 + 31498087 = 31498090
- 47 + 31498043 = 31498090
- 83 + 31498007 = 31498090
- 149 + 31497941 = 31498090
- 227 + 31497863 = 31498090
- 263 + 31497827 = 31498090
- 293 + 31497797 = 31498090
- 317 + 31497773 = 31498090
Showing the first eight; more decompositions exist.
