Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455670, here are decompositions:
- 23 + 31455647 = 31455670
- 47 + 31455623 = 31455670
- 137 + 31455533 = 31455670
- 149 + 31455521 = 31455670
- 167 + 31455503 = 31455670
- 251 + 31455419 = 31455670
- 401 + 31455269 = 31455670
- 431 + 31455239 = 31455670
Showing the first eight; more decompositions exist.
