Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493448, here are decompositions:
- 5 + 31493443 = 31493448
- 29 + 31493419 = 31493448
- 71 + 31493377 = 31493448
- 101 + 31493347 = 31493448
- 109 + 31493339 = 31493448
- 127 + 31493321 = 31493448
- 157 + 31493291 = 31493448
- 197 + 31493251 = 31493448
Showing the first eight; more decompositions exist.
