Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61646, here are decompositions:

3 + 61643 = 61646
19 + 61627 = 61646
37 + 61609 = 61646
43 + 61603 = 61646
103 + 61543 = 61646
127 + 61519 = 61646
139 + 61507 = 61646
163 + 61483 = 61646

Showing the first eight; more decompositions exist.
