Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461382, here are decompositions:

41 + 31461341 = 31461382
89 + 31461293 = 31461382
101 + 31461281 = 31461382
191 + 31461191 = 31461382
233 + 31461149 = 31461382
269 + 31461113 = 31461382
431 + 31460951 = 31461382
503 + 31460879 = 31461382

Showing the first eight; more decompositions exist.
