Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111806, here are decompositions:

7 + 111799 = 111806
73 + 111733 = 111806
109 + 111697 = 111806
139 + 111667 = 111806
229 + 111577 = 111806
313 + 111493 = 111806
367 + 111439 = 111806
379 + 111427 = 111806

Showing the first eight; more decompositions exist.
