Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503350, here are decompositions:

7 + 31503343 = 31503350
13 + 31503337 = 31503350
19 + 31503331 = 31503350
37 + 31503313 = 31503350
199 + 31503151 = 31503350
211 + 31503139 = 31503350
397 + 31502953 = 31503350
409 + 31502941 = 31503350

Showing the first eight; more decompositions exist.
