Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503050, here are decompositions:

97 + 31502953 = 31503050
109 + 31502941 = 31503050
127 + 31502923 = 31503050
193 + 31502857 = 31503050
307 + 31502743 = 31503050
349 + 31502701 = 31503050
463 + 31502587 = 31503050
487 + 31502563 = 31503050

Showing the first eight; more decompositions exist.
