Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453362, here are decompositions:

29 + 31453333 = 31453362
41 + 31453321 = 31453362
79 + 31453283 = 31453362
113 + 31453249 = 31453362
181 + 31453181 = 31453362
191 + 31453171 = 31453362
229 + 31453133 = 31453362
389 + 31452973 = 31453362

Showing the first eight; more decompositions exist.
