Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541084, here are decompositions:

13 + 31541071 = 31541084
37 + 31541047 = 31541084
67 + 31541017 = 31541084
163 + 31540921 = 31541084
271 + 31540813 = 31541084
433 + 31540651 = 31541084
613 + 31540471 = 31541084
643 + 31540441 = 31541084

Showing the first eight; more decompositions exist.
