Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560342, here are decompositions:

43 + 31560299 = 31560342
103 + 31560239 = 31560342
109 + 31560233 = 31560342
263 + 31560079 = 31560342
269 + 31560073 = 31560342
283 + 31560059 = 31560342
313 + 31560029 = 31560342
353 + 31559989 = 31560342

Showing the first eight; more decompositions exist.
