Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628342, here are decompositions:

73 + 31628269 = 31628342
103 + 31628239 = 31628342
181 + 31628161 = 31628342
241 + 31628101 = 31628342
331 + 31628011 = 31628342
373 + 31627969 = 31628342
439 + 31627903 = 31628342
463 + 31627879 = 31628342

Showing the first eight; more decompositions exist.
