Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175778, here are decompositions:

19 + 175759 = 175778
79 + 175699 = 175778
157 + 175621 = 175778
331 + 175447 = 175778
367 + 175411 = 175778
487 + 175291 = 175778
709 + 175069 = 175778
739 + 175039 = 175778

Showing the first eight; more decompositions exist.
