Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501244, here are decompositions:

13 + 31501231 = 31501244
43 + 31501201 = 31501244
127 + 31501117 = 31501244
163 + 31501081 = 31501244
277 + 31500967 = 31501244
373 + 31500871 = 31501244
757 + 31500487 = 31501244
787 + 31500457 = 31501244

Showing the first eight; more decompositions exist.
