Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523000, here are decompositions:
- 13 + 31522987 = 31523000
- 127 + 31522873 = 31523000
- 283 + 31522717 = 31523000
- 307 + 31522693 = 31523000
- 331 + 31522669 = 31523000
- 337 + 31522663 = 31523000
- 367 + 31522633 = 31523000
- 409 + 31522591 = 31523000
Showing the first eight; more decompositions exist.
