Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459382, here are decompositions:
- 43 + 31459339 = 31459382
- 61 + 31459321 = 31459382
- 181 + 31459201 = 31459382
- 271 + 31459111 = 31459382
- 313 + 31459069 = 31459382
- 673 + 31458709 = 31459382
- 739 + 31458643 = 31459382
- 751 + 31458631 = 31459382
Showing the first eight; more decompositions exist.
