Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547754, here are decompositions:
- 5 + 31547749 = 31547754
- 23 + 31547731 = 31547754
- 47 + 31547707 = 31547754
- 53 + 31547701 = 31547754
- 61 + 31547693 = 31547754
- 71 + 31547683 = 31547754
- 83 + 31547671 = 31547754
- 113 + 31547641 = 31547754
Showing the first eight; more decompositions exist.
