Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477532, here are decompositions:

19 + 31477513 = 31477532
103 + 31477429 = 31477532
109 + 31477423 = 31477532
181 + 31477351 = 31477532
211 + 31477321 = 31477532
241 + 31477291 = 31477532
421 + 31477111 = 31477532
433 + 31477099 = 31477532

Showing the first eight; more decompositions exist.
