Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523562, here are decompositions:
- 23 + 31523539 = 31523562
- 41 + 31523521 = 31523562
- 89 + 31523473 = 31523562
- 101 + 31523461 = 31523562
- 151 + 31523411 = 31523562
- 163 + 31523399 = 31523562
- 181 + 31523381 = 31523562
- 233 + 31523329 = 31523562
Showing the first eight; more decompositions exist.
