Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541846, here are decompositions:

19 + 31541827 = 31541846
109 + 31541737 = 31541846
139 + 31541707 = 31541846
277 + 31541569 = 31541846
283 + 31541563 = 31541846
337 + 31541509 = 31541846
379 + 31541467 = 31541846
397 + 31541449 = 31541846

Showing the first eight; more decompositions exist.
