Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481134, here are decompositions:

11 + 31481123 = 31481134
23 + 31481111 = 31481134
233 + 31480901 = 31481134
401 + 31480733 = 31481134
701 + 31480433 = 31481134
743 + 31480391 = 31481134
761 + 31480373 = 31481134
1031 + 31480103 = 31481134

Showing the first eight; more decompositions exist.
