Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541030, here are decompositions:

13 + 31541017 = 31541030
109 + 31540921 = 31541030
163 + 31540867 = 31541030
193 + 31540837 = 31541030
307 + 31540723 = 31541030
331 + 31540699 = 31541030
337 + 31540693 = 31541030
373 + 31540657 = 31541030

Showing the first eight; more decompositions exist.
