Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453436, here are decompositions:

43 + 31453393 = 31453436
103 + 31453333 = 31453436
229 + 31453207 = 31453436
277 + 31453159 = 31453436
397 + 31453039 = 31453436
463 + 31452973 = 31453436
577 + 31452859 = 31453436
607 + 31452829 = 31453436

Showing the first eight; more decompositions exist.
