Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527520, here are decompositions:
- 23 + 31527497 = 31527520
- 29 + 31527491 = 31527520
- 107 + 31527413 = 31527520
- 113 + 31527407 = 31527520
- 131 + 31527389 = 31527520
- 197 + 31527323 = 31527520
- 347 + 31527173 = 31527520
- 389 + 31527131 = 31527520
Showing the first eight; more decompositions exist.
