Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80572, here are decompositions:

5 + 80567 = 80572
59 + 80513 = 80572
83 + 80489 = 80572
101 + 80471 = 80572
263 + 80309 = 80572
293 + 80279 = 80572
419 + 80153 = 80572
431 + 80141 = 80572

Showing the first eight; more decompositions exist.
