Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61806, here are decompositions:

83 + 61723 = 61806
89 + 61717 = 61806
103 + 61703 = 61806
139 + 61667 = 61806
149 + 61657 = 61806
163 + 61643 = 61806
179 + 61627 = 61806
193 + 61613 = 61806

Showing the first eight; more decompositions exist.
