Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497304, here are decompositions:
- 5 + 31497299 = 31497304
- 11 + 31497293 = 31497304
- 17 + 31497287 = 31497304
- 53 + 31497251 = 31497304
- 233 + 31497071 = 31497304
- 347 + 31496957 = 31497304
- 383 + 31496921 = 31497304
- 431 + 31496873 = 31497304
Showing the first eight; more decompositions exist.
