Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448048, here are decompositions:
- 31 + 31448017 = 31448048
- 61 + 31447987 = 31448048
- 97 + 31447951 = 31448048
- 211 + 31447837 = 31448048
- 367 + 31447681 = 31448048
- 421 + 31447627 = 31448048
- 571 + 31447477 = 31448048
- 607 + 31447441 = 31448048
Showing the first eight; more decompositions exist.
