Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503394, here are decompositions:

53 + 31503341 = 31503394
71 + 31503323 = 31503394
191 + 31503203 = 31503394
227 + 31503167 = 31503394
401 + 31502993 = 31503394
431 + 31502963 = 31503394
467 + 31502927 = 31503394
617 + 31502777 = 31503394

Showing the first eight; more decompositions exist.
