Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541060, here are decompositions:

13 + 31541047 = 31541060
43 + 31541017 = 31541060
139 + 31540921 = 31541060
193 + 31540867 = 31541060
223 + 31540837 = 31541060
277 + 31540783 = 31541060
337 + 31540723 = 31541060
367 + 31540693 = 31541060

Showing the first eight; more decompositions exist.
