Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483684, here are decompositions:

101 + 31483583 = 31483684
107 + 31483577 = 31483684
131 + 31483553 = 31483684
137 + 31483547 = 31483684
191 + 31483493 = 31483684
227 + 31483457 = 31483684
251 + 31483433 = 31483684
293 + 31483391 = 31483684

Showing the first eight; more decompositions exist.
