Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577822, here are decompositions:

43 + 31577779 = 31577822
163 + 31577659 = 31577822
229 + 31577593 = 31577822
313 + 31577509 = 31577822
349 + 31577473 = 31577822
421 + 31577401 = 31577822
433 + 31577389 = 31577822
439 + 31577383 = 31577822

Showing the first eight; more decompositions exist.
