Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68564, here are decompositions:

43 + 68521 = 68564
73 + 68491 = 68564
127 + 68437 = 68564
193 + 68371 = 68564
283 + 68281 = 68564
337 + 68227 = 68564
523 + 68041 = 68564
541 + 68023 = 68564

Showing the first eight; more decompositions exist.
