Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489750, here are decompositions:
- 3 + 31489747 = 31489750
- 29 + 31489721 = 31489750
- 41 + 31489709 = 31489750
- 137 + 31489613 = 31489750
- 179 + 31489571 = 31489750
- 317 + 31489433 = 31489750
- 359 + 31489391 = 31489750
- 401 + 31489349 = 31489750
Showing the first eight; more decompositions exist.
