Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490348, here are decompositions:
- 61 + 31490287 = 31490348
- 67 + 31490281 = 31490348
- 199 + 31490149 = 31490348
- 229 + 31490119 = 31490348
- 271 + 31490077 = 31490348
- 349 + 31489999 = 31490348
- 601 + 31489747 = 31490348
- 829 + 31489519 = 31490348
Showing the first eight; more decompositions exist.
