Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480684, here are decompositions:

3 + 31480681 = 31480684
251 + 31480433 = 31480684
293 + 31480391 = 31480684
311 + 31480373 = 31480684
317 + 31480367 = 31480684
593 + 31480091 = 31480684
827 + 31479857 = 31480684
863 + 31479821 = 31480684

Showing the first eight; more decompositions exist.
