Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162578, here are decompositions:

61 + 162517 = 162578
79 + 162499 = 162578
127 + 162451 = 162578
139 + 162439 = 162578
349 + 162229 = 162578
487 + 162091 = 162578
499 + 162079 = 162578
571 + 162007 = 162578

Showing the first eight; more decompositions exist.
