Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520304, here are decompositions:
- 5 + 31520299 = 31520304
- 61 + 31520243 = 31520304
- 71 + 31520233 = 31520304
- 103 + 31520201 = 31520304
- 131 + 31520173 = 31520304
- 163 + 31520141 = 31520304
- 293 + 31520011 = 31520304
- 317 + 31519987 = 31520304
Showing the first eight; more decompositions exist.
