Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105572, here are decompositions:

31 + 105541 = 105572
43 + 105529 = 105572
73 + 105499 = 105572
193 + 105379 = 105572
199 + 105373 = 105572
211 + 105361 = 105572
241 + 105331 = 105572
373 + 105199 = 105572

Showing the first eight; more decompositions exist.
