Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501504, here are decompositions:

71 + 31501433 = 31501504
101 + 31501403 = 31501504
173 + 31501331 = 31501504
191 + 31501313 = 31501504
257 + 31501247 = 31501504
443 + 31501061 = 31501504
467 + 31501037 = 31501504
557 + 31500947 = 31501504

Showing the first eight; more decompositions exist.
