Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 468140, here are decompositions:

3 + 468137 = 468140
7 + 468133 = 468140
19 + 468121 = 468140
31 + 468109 = 468140
61 + 468079 = 468140
73 + 468067 = 468140
139 + 468001 = 468140
163 + 467977 = 468140

Showing the first eight; more decompositions exist.
