Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537086, here are decompositions:
- 37 + 31537049 = 31537086
- 43 + 31537043 = 31537086
- 47 + 31537039 = 31537086
- 59 + 31537027 = 31537086
- 83 + 31537003 = 31537086
- 103 + 31536983 = 31537086
- 127 + 31536959 = 31537086
- 149 + 31536937 = 31537086
Showing the first eight; more decompositions exist.
