Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450362, here are decompositions:

11 + 31450351 = 31450362
71 + 31450291 = 31450362
199 + 31450163 = 31450362
263 + 31450099 = 31450362
269 + 31450093 = 31450362
331 + 31450031 = 31450362
373 + 31449989 = 31450362
431 + 31449931 = 31450362

Showing the first eight; more decompositions exist.
