Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455576, here are decompositions:
- 43 + 31455533 = 31455576
- 73 + 31455503 = 31455576
- 127 + 31455449 = 31455576
- 149 + 31455427 = 31455576
- 157 + 31455419 = 31455576
- 167 + 31455409 = 31455576
- 179 + 31455397 = 31455576
- 263 + 31455313 = 31455576
Showing the first eight; more decompositions exist.
