Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480444, here are decompositions:
- 3 + 31480441 = 31480444
- 11 + 31480433 = 31480444
- 53 + 31480391 = 31480444
- 71 + 31480373 = 31480444
- 353 + 31480091 = 31480444
- 383 + 31480061 = 31480444
- 563 + 31479881 = 31480444
- 587 + 31479857 = 31480444
Showing the first eight; more decompositions exist.
