Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541048, here are decompositions:

31 + 31541017 = 31541048
109 + 31540939 = 31541048
127 + 31540921 = 31541048
181 + 31540867 = 31541048
211 + 31540837 = 31541048
349 + 31540699 = 31541048
379 + 31540669 = 31541048
397 + 31540651 = 31541048

Showing the first eight; more decompositions exist.
