Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471622, here are decompositions:
- 31 + 31471591 = 31471622
- 43 + 31471579 = 31471622
- 73 + 31471549 = 31471622
- 211 + 31471411 = 31471622
- 409 + 31471213 = 31471622
- 499 + 31471123 = 31471622
- 571 + 31471051 = 31471622
- 631 + 31470991 = 31471622
Showing the first eight; more decompositions exist.
