Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501434, here are decompositions:

7 + 31501427 = 31501434
31 + 31501403 = 31501434
47 + 31501387 = 31501434
73 + 31501361 = 31501434
101 + 31501333 = 31501434
103 + 31501331 = 31501434
113 + 31501321 = 31501434
131 + 31501303 = 31501434

Showing the first eight; more decompositions exist.
