Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625474, here are decompositions:
- 7 + 31625467 = 31625474
- 43 + 31625431 = 31625474
- 73 + 31625401 = 31625474
- 193 + 31625281 = 31625474
- 211 + 31625263 = 31625474
- 523 + 31624951 = 31625474
- 547 + 31624927 = 31625474
- 613 + 31624861 = 31625474
Showing the first eight; more decompositions exist.
