Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607586, here are decompositions:

5 + 31607581 = 31607586
7 + 31607579 = 31607586
83 + 31607503 = 31607586
97 + 31607489 = 31607586
113 + 31607473 = 31607586
137 + 31607449 = 31607586
139 + 31607447 = 31607586
163 + 31607423 = 31607586

Showing the first eight; more decompositions exist.
