Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459200, here are decompositions:
- 67 + 31459133 = 31459200
- 89 + 31459111 = 31459200
- 107 + 31459093 = 31459200
- 127 + 31459073 = 31459200
- 131 + 31459069 = 31459200
- 137 + 31459063 = 31459200
- 181 + 31459019 = 31459200
- 233 + 31458967 = 31459200
Showing the first eight; more decompositions exist.
