Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480744, here are decompositions:

11 + 31480733 = 31480744
311 + 31480433 = 31480744
353 + 31480391 = 31480744
641 + 31480103 = 31480744
653 + 31480091 = 31480744
683 + 31480061 = 31480744
797 + 31479947 = 31480744
863 + 31479881 = 31480744

Showing the first eight; more decompositions exist.
