Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453054, here are decompositions:

251 + 31452803 = 31453054
431 + 31452623 = 31453054
467 + 31452587 = 31453054
557 + 31452497 = 31453054
593 + 31452461 = 31453054
653 + 31452401 = 31453054
821 + 31452233 = 31453054
881 + 31452173 = 31453054

Showing the first eight; more decompositions exist.
