Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626952, here are decompositions:

53 + 31626899 = 31626952
59 + 31626893 = 31626952
83 + 31626869 = 31626952
113 + 31626839 = 31626952
263 + 31626689 = 31626952
389 + 31626563 = 31626952
419 + 31626533 = 31626952
491 + 31626461 = 31626952

Showing the first eight; more decompositions exist.
