Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444836, here are decompositions:
- 23 + 31444813 = 31444836
- 29 + 31444807 = 31444836
- 47 + 31444789 = 31444836
- 109 + 31444727 = 31444836
- 113 + 31444723 = 31444836
- 193 + 31444643 = 31444836
- 263 + 31444573 = 31444836
- 277 + 31444559 = 31444836
Showing the first eight; more decompositions exist.
