Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027172, here are decompositions:

19 + 1027153 = 1027172
43 + 1027129 = 1027172
193 + 1026979 = 1027172
229 + 1026943 = 1027172
313 + 1026859 = 1027172
373 + 1026799 = 1027172
439 + 1026733 = 1027172
463 + 1026709 = 1027172

Showing the first eight; more decompositions exist.
