Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513572, here are decompositions:

43 + 513529 = 513572
61 + 513511 = 513572
463 + 513109 = 513572
541 + 513031 = 513572
571 + 513001 = 513572
613 + 512959 = 513572
643 + 512929 = 513572
673 + 512899 = 513572

Showing the first eight; more decompositions exist.
