Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501304, here are decompositions:

73 + 31501231 = 31501304
103 + 31501201 = 31501304
223 + 31501081 = 31501304
337 + 31500967 = 31501304
433 + 31500871 = 31501304
487 + 31500817 = 31501304
613 + 31500691 = 31501304
853 + 31500451 = 31501304

Showing the first eight; more decompositions exist.
