Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541422, here are decompositions:

5 + 31541417 = 31541422
23 + 31541399 = 31541422
179 + 31541243 = 31541422
281 + 31541141 = 31541422
293 + 31541129 = 31541422
383 + 31541039 = 31541422
401 + 31541021 = 31541422
431 + 31540991 = 31541422

Showing the first eight; more decompositions exist.
