Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449470, here are decompositions:
- 7 + 31449463 = 31449470
- 61 + 31449409 = 31449470
- 67 + 31449403 = 31449470
- 97 + 31449373 = 31449470
- 109 + 31449361 = 31449470
- 181 + 31449289 = 31449470
- 211 + 31449259 = 31449470
- 223 + 31449247 = 31449470
Showing the first eight; more decompositions exist.
