Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504260, here are decompositions:

31 + 31504229 = 31504260
41 + 31504219 = 31504260
59 + 31504201 = 31504260
71 + 31504189 = 31504260
127 + 31504133 = 31504260
131 + 31504129 = 31504260
157 + 31504103 = 31504260
163 + 31504097 = 31504260

Showing the first eight; more decompositions exist.
