Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450342, here are decompositions:

29 + 31450313 = 31450342
71 + 31450271 = 31450342
179 + 31450163 = 31450342
239 + 31450103 = 31450342
281 + 31450061 = 31450342
311 + 31450031 = 31450342
353 + 31449989 = 31450342
419 + 31449923 = 31450342

Showing the first eight; more decompositions exist.
