Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464620, here are decompositions:
- 3 + 31464617 = 31464620
- 43 + 31464577 = 31464620
- 73 + 31464547 = 31464620
- 127 + 31464493 = 31464620
- 139 + 31464481 = 31464620
- 157 + 31464463 = 31464620
- 181 + 31464439 = 31464620
- 193 + 31464427 = 31464620
Showing the first eight; more decompositions exist.
