Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523192, here are decompositions:

31 + 31523161 = 31523192
61 + 31523131 = 31523192
73 + 31523119 = 31523192
79 + 31523113 = 31523192
139 + 31523053 = 31523192
241 + 31522951 = 31523192
499 + 31522693 = 31523192
523 + 31522669 = 31523192

Showing the first eight; more decompositions exist.
