Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450848, here are decompositions:
- 5 + 31450843 = 31450848
- 7 + 31450841 = 31450848
- 19 + 31450829 = 31450848
- 47 + 31450801 = 31450848
- 59 + 31450789 = 31450848
- 61 + 31450787 = 31450848
- 67 + 31450781 = 31450848
- 109 + 31450739 = 31450848
Showing the first eight; more decompositions exist.
