Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453300, here are decompositions:

17 + 31453283 = 31453300
59 + 31453241 = 31453300
107 + 31453193 = 31453300
167 + 31453133 = 31453300
449 + 31452851 = 31453300
569 + 31452731 = 31453300
617 + 31452683 = 31453300
677 + 31452623 = 31453300

Showing the first eight; more decompositions exist.
