Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453342, here are decompositions:

59 + 31453283 = 31453342
101 + 31453241 = 31453342
149 + 31453193 = 31453342
491 + 31452851 = 31453342
593 + 31452749 = 31453342
659 + 31452683 = 31453342
719 + 31452623 = 31453342
743 + 31452599 = 31453342

Showing the first eight; more decompositions exist.
