Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564304, here are decompositions:
- 43 + 31564261 = 31564304
- 61 + 31564243 = 31564304
- 67 + 31564237 = 31564304
- 97 + 31564207 = 31564304
- 157 + 31564147 = 31564304
- 337 + 31563967 = 31564304
- 367 + 31563937 = 31564304
- 397 + 31563907 = 31564304
Showing the first eight; more decompositions exist.
