Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503412, here are decompositions:

71 + 31503341 = 31503412
89 + 31503323 = 31503412
233 + 31503179 = 31503412
293 + 31503119 = 31503412
359 + 31503053 = 31503412
419 + 31502993 = 31503412
449 + 31502963 = 31503412
929 + 31502483 = 31503412

Showing the first eight; more decompositions exist.
