Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61722, here are decompositions:

5 + 61717 = 61722
19 + 61703 = 61722
41 + 61681 = 61722
71 + 61651 = 61722
79 + 61643 = 61722
109 + 61613 = 61722
113 + 61609 = 61722
139 + 61583 = 61722

Showing the first eight; more decompositions exist.
