Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504230, here are decompositions:

11 + 31504219 = 31504230
29 + 31504201 = 31504230
41 + 31504189 = 31504230
47 + 31504183 = 31504230
97 + 31504133 = 31504230
101 + 31504129 = 31504230
103 + 31504127 = 31504230
127 + 31504103 = 31504230

Showing the first eight; more decompositions exist.
