Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461370, here are decompositions:

29 + 31461341 = 31461370
89 + 31461281 = 31461370
179 + 31461191 = 31461370
191 + 31461179 = 31461370
197 + 31461173 = 31461370
257 + 31461113 = 31461370
359 + 31461011 = 31461370
419 + 31460951 = 31461370

Showing the first eight; more decompositions exist.
