Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507626, here are decompositions:

19 + 31507607 = 31507626
43 + 31507583 = 31507626
53 + 31507573 = 31507626
103 + 31507523 = 31507626
167 + 31507459 = 31507626
223 + 31507403 = 31507626
263 + 31507363 = 31507626
307 + 31507319 = 31507626

Showing the first eight; more decompositions exist.
