Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123572, here are decompositions:

19 + 123553 = 123572
73 + 123499 = 123572
79 + 123493 = 123572
139 + 123433 = 123572
193 + 123379 = 123572
199 + 123373 = 123572
283 + 123289 = 123572
313 + 123259 = 123572

Showing the first eight; more decompositions exist.
