Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504254, here are decompositions:

53 + 31504201 = 31504254
71 + 31504183 = 31504254
127 + 31504127 = 31504254
151 + 31504103 = 31504254
157 + 31504097 = 31504254
167 + 31504087 = 31504254
241 + 31504013 = 31504254
277 + 31503977 = 31504254

Showing the first eight; more decompositions exist.
