Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453334, here are decompositions:

13 + 31453321 = 31453334
67 + 31453267 = 31453334
127 + 31453207 = 31453334
163 + 31453171 = 31453334
193 + 31453141 = 31453334
313 + 31453021 = 31453334
433 + 31452901 = 31453334
541 + 31452793 = 31453334

Showing the first eight; more decompositions exist.
