Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109812, here are decompositions:

5 + 109807 = 109812
19 + 109793 = 109812
23 + 109789 = 109812
61 + 109751 = 109812
71 + 109741 = 109812
139 + 109673 = 109812
149 + 109663 = 109812
151 + 109661 = 109812

Showing the first eight; more decompositions exist.
