Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68572, here are decompositions:

5 + 68567 = 68572
29 + 68543 = 68572
41 + 68531 = 68572
71 + 68501 = 68572
83 + 68489 = 68572
89 + 68483 = 68572
173 + 68399 = 68572
293 + 68279 = 68572

Showing the first eight; more decompositions exist.
