Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504250, here are decompositions:

31 + 31504219 = 31504250
61 + 31504189 = 31504250
67 + 31504183 = 31504250
163 + 31504087 = 31504250
199 + 31504051 = 31504250
277 + 31503973 = 31504250
367 + 31503883 = 31504250
397 + 31503853 = 31504250

Showing the first eight; more decompositions exist.
