Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480954, here are decompositions:

5 + 31480949 = 31480954
41 + 31480913 = 31480954
53 + 31480901 = 31480954
191 + 31480763 = 31480954
521 + 31480433 = 31480954
563 + 31480391 = 31480954
587 + 31480367 = 31480954
863 + 31480091 = 31480954

Showing the first eight; more decompositions exist.
