Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468370, here are decompositions:

127 + 31468243 = 31468370
139 + 31468231 = 31468370
211 + 31468159 = 31468370
223 + 31468147 = 31468370
421 + 31467949 = 31468370
433 + 31467937 = 31468370
523 + 31467847 = 31468370
541 + 31467829 = 31468370

Showing the first eight; more decompositions exist.
