Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453822, here are decompositions:

89 + 31453733 = 31453822
251 + 31453571 = 31453822
293 + 31453529 = 31453822
359 + 31453463 = 31453822
401 + 31453421 = 31453822
431 + 31453391 = 31453822
461 + 31453361 = 31453822
641 + 31453181 = 31453822

Showing the first eight; more decompositions exist.
