Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509050, here are decompositions:

19 + 31509031 = 31509050
103 + 31508947 = 31509050
163 + 31508887 = 31509050
193 + 31508857 = 31509050
337 + 31508713 = 31509050
367 + 31508683 = 31509050
373 + 31508677 = 31509050
379 + 31508671 = 31509050

Showing the first eight; more decompositions exist.
