Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453162, here are decompositions:

3 + 31453159 = 31453162
5 + 31453157 = 31453162
29 + 31453133 = 31453162
311 + 31452851 = 31453162
359 + 31452803 = 31453162
431 + 31452731 = 31453162
443 + 31452719 = 31453162
479 + 31452683 = 31453162

Showing the first eight; more decompositions exist.
