Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541550, here are decompositions:

23 + 31541527 = 31541550
41 + 31541509 = 31541550
43 + 31541507 = 31541550
67 + 31541483 = 31541550
83 + 31541467 = 31541550
101 + 31541449 = 31541550
113 + 31541437 = 31541550
149 + 31541401 = 31541550

Showing the first eight; more decompositions exist.
