Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468250, here are decompositions:

3 + 31468247 = 31468250
7 + 31468243 = 31468250
19 + 31468231 = 31468250
103 + 31468147 = 31468250
223 + 31468027 = 31468250
283 + 31467967 = 31468250
313 + 31467937 = 31468250
397 + 31467853 = 31468250

Showing the first eight; more decompositions exist.
