Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477604, here are decompositions:

43 + 31477561 = 31477604
61 + 31477543 = 31477604
97 + 31477507 = 31477604
157 + 31477447 = 31477604
181 + 31477423 = 31477604
283 + 31477321 = 31477604
313 + 31477291 = 31477604
397 + 31477207 = 31477604

Showing the first eight; more decompositions exist.
