Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101838, here are decompositions:

5 + 101833 = 101838
31 + 101807 = 101838
41 + 101797 = 101838
67 + 101771 = 101838
89 + 101749 = 101838
97 + 101741 = 101838
101 + 101737 = 101838
137 + 101701 = 101838

Showing the first eight; more decompositions exist.
