Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503010, here are decompositions:

17 + 31502993 = 31503010
47 + 31502963 = 31503010
83 + 31502927 = 31503010
113 + 31502897 = 31503010
233 + 31502777 = 31503010
311 + 31502699 = 31503010
449 + 31502561 = 31503010
521 + 31502489 = 31503010

Showing the first eight; more decompositions exist.
