Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480284, here are decompositions:

83 + 31480201 = 31480284
167 + 31480117 = 31480284
181 + 31480103 = 31480284
193 + 31480091 = 31480284
223 + 31480061 = 31480284
263 + 31480021 = 31480284
337 + 31479947 = 31480284
463 + 31479821 = 31480284

Showing the first eight; more decompositions exist.
