Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478914, here are decompositions:
- 3 + 31478911 = 31478914
- 83 + 31478831 = 31478914
- 107 + 31478807 = 31478914
- 347 + 31478567 = 31478914
- 431 + 31478483 = 31478914
- 443 + 31478471 = 31478914
- 503 + 31478411 = 31478914
- 521 + 31478393 = 31478914
Showing the first eight; more decompositions exist.
