Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539626, here are decompositions:

43 + 31539583 = 31539626
103 + 31539523 = 31539626
127 + 31539499 = 31539626
277 + 31539349 = 31539626
337 + 31539289 = 31539626
397 + 31539229 = 31539626
463 + 31539163 = 31539626
619 + 31539007 = 31539626

Showing the first eight; more decompositions exist.
