Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604884, here are decompositions:
- 137 + 31604747 = 31604884
- 197 + 31604687 = 31604884
- 257 + 31604627 = 31604884
- 281 + 31604603 = 31604884
- 383 + 31604501 = 31604884
- 431 + 31604453 = 31604884
- 587 + 31604297 = 31604884
- 827 + 31604057 = 31604884
Showing the first eight; more decompositions exist.
