Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503654, here are decompositions:

11 + 31503643 = 31503654
23 + 31503631 = 31503654
97 + 31503557 = 31503654
101 + 31503553 = 31503654
211 + 31503443 = 31503654
293 + 31503361 = 31503654
311 + 31503343 = 31503654
313 + 31503341 = 31503654

Showing the first eight; more decompositions exist.
