Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583532, here are decompositions:
- 5 + 31583527 = 31583532
- 11 + 31583521 = 31583532
- 23 + 31583509 = 31583532
- 83 + 31583449 = 31583532
- 109 + 31583423 = 31583532
- 179 + 31583353 = 31583532
- 181 + 31583351 = 31583532
- 251 + 31583281 = 31583532
Showing the first eight; more decompositions exist.
