Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501334, here are decompositions:

3 + 31501331 = 31501334
13 + 31501321 = 31501334
31 + 31501303 = 31501334
103 + 31501231 = 31501334
367 + 31500967 = 31501334
463 + 31500871 = 31501334
541 + 31500793 = 31501334
643 + 31500691 = 31501334

Showing the first eight; more decompositions exist.
