Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19562, here are decompositions:

3 + 19559 = 19562
19 + 19543 = 19562
31 + 19531 = 19562
61 + 19501 = 19562
73 + 19489 = 19562
79 + 19483 = 19562
139 + 19423 = 19562
181 + 19381 = 19562

Showing the first eight; more decompositions exist.
