Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161526, here are decompositions:

5 + 161521 = 161526
19 + 161507 = 161526
23 + 161503 = 161526
67 + 161459 = 161526
73 + 161453 = 161526
139 + 161387 = 161526
149 + 161377 = 161526
163 + 161363 = 161526

Showing the first eight; more decompositions exist.
