Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535190, here are decompositions:
- 7 + 31535183 = 31535190
- 17 + 31535173 = 31535190
- 19 + 31535171 = 31535190
- 47 + 31535143 = 31535190
- 59 + 31535131 = 31535190
- 67 + 31535123 = 31535190
- 83 + 31535107 = 31535190
- 107 + 31535083 = 31535190
Showing the first eight; more decompositions exist.
