Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450252, here are decompositions:

5 + 31450247 = 31450252
89 + 31450163 = 31450252
149 + 31450103 = 31450252
191 + 31450061 = 31450252
263 + 31449989 = 31450252
461 + 31449791 = 31450252
563 + 31449689 = 31450252
641 + 31449611 = 31450252

Showing the first eight; more decompositions exist.
