Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504284, here are decompositions:

83 + 31504201 = 31504284
101 + 31504183 = 31504284
151 + 31504133 = 31504284
157 + 31504127 = 31504284
181 + 31504103 = 31504284
197 + 31504087 = 31504284
233 + 31504051 = 31504284
271 + 31504013 = 31504284

Showing the first eight; more decompositions exist.
