Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583232, here are decompositions:
- 61 + 31583171 = 31583232
- 73 + 31583159 = 31583232
- 101 + 31583131 = 31583232
- 151 + 31583081 = 31583232
- 181 + 31583051 = 31583232
- 199 + 31583033 = 31583232
- 251 + 31582981 = 31583232
- 271 + 31582961 = 31583232
Showing the first eight; more decompositions exist.
