Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459328, here are decompositions:
- 7 + 31459321 = 31459328
- 37 + 31459291 = 31459328
- 67 + 31459261 = 31459328
- 127 + 31459201 = 31459328
- 421 + 31458907 = 31459328
- 499 + 31458829 = 31459328
- 541 + 31458787 = 31459328
- 619 + 31458709 = 31459328
Showing the first eight; more decompositions exist.
