Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37872, here are decompositions:
- 11 + 37861 = 37872
- 19 + 37853 = 37872
- 41 + 37831 = 37872
- 59 + 37813 = 37872
- 61 + 37811 = 37872
- 73 + 37799 = 37872
- 89 + 37783 = 37872
- 173 + 37699 = 37872
Showing the first eight; more decompositions exist.
