Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541126, here are decompositions:

13 + 31541113 = 31541126
79 + 31541047 = 31541126
109 + 31541017 = 31541126
313 + 31540813 = 31541126
433 + 31540693 = 31541126
457 + 31540669 = 31541126
709 + 31540417 = 31541126
787 + 31540339 = 31541126

Showing the first eight; more decompositions exist.
