Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453084, here are decompositions:

107 + 31452977 = 31453084
233 + 31452851 = 31453084
281 + 31452803 = 31453084
353 + 31452731 = 31453084
401 + 31452683 = 31453084
461 + 31452623 = 31453084
557 + 31452527 = 31453084
563 + 31452521 = 31453084

Showing the first eight; more decompositions exist.
