Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111572, here are decompositions:

79 + 111493 = 111572
163 + 111409 = 111572
199 + 111373 = 111572
271 + 111301 = 111572
463 + 111109 = 111572
523 + 111049 = 111572
541 + 111031 = 111572
673 + 110899 = 111572

Showing the first eight; more decompositions exist.
