Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609474, here are decompositions:
- 5 + 31609469 = 31609474
- 11 + 31609463 = 31609474
- 23 + 31609451 = 31609474
- 251 + 31609223 = 31609474
- 383 + 31609091 = 31609474
- 443 + 31609031 = 31609474
- 503 + 31608971 = 31609474
- 521 + 31608953 = 31609474
Showing the first eight; more decompositions exist.
