Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540192, here are decompositions:

3 + 31540189 = 31540192
11 + 31540181 = 31540192
29 + 31540163 = 31540192
83 + 31540109 = 31540192
179 + 31540013 = 31540192
353 + 31539839 = 31540192
479 + 31539713 = 31540192
521 + 31539671 = 31540192

Showing the first eight; more decompositions exist.
