Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541018, here are decompositions:

79 + 31540939 = 31541018
97 + 31540921 = 31541018
151 + 31540867 = 31541018
181 + 31540837 = 31541018
349 + 31540669 = 31541018
367 + 31540651 = 31541018
547 + 31540471 = 31541018
577 + 31540441 = 31541018

Showing the first eight; more decompositions exist.
