Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504358, here are decompositions:

7 + 31504351 = 31504358
31 + 31504327 = 31504358
139 + 31504219 = 31504358
157 + 31504201 = 31504358
229 + 31504129 = 31504358
271 + 31504087 = 31504358
307 + 31504051 = 31504358
397 + 31503961 = 31504358

Showing the first eight; more decompositions exist.
