Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504266, here are decompositions:

37 + 31504229 = 31504266
47 + 31504219 = 31504266
83 + 31504183 = 31504266
137 + 31504129 = 31504266
139 + 31504127 = 31504266
163 + 31504103 = 31504266
179 + 31504087 = 31504266
229 + 31504037 = 31504266

Showing the first eight; more decompositions exist.
