Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523472, here are decompositions:
- 5 + 31523467 = 31523472
- 11 + 31523461 = 31523472
- 31 + 31523441 = 31523472
- 53 + 31523419 = 31523472
- 61 + 31523411 = 31523472
- 73 + 31523399 = 31523472
- 163 + 31523309 = 31523472
- 179 + 31523293 = 31523472
Showing the first eight; more decompositions exist.
