Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626524, here are decompositions:

31 + 31626493 = 31626524
43 + 31626481 = 31626524
103 + 31626421 = 31626524
157 + 31626367 = 31626524
277 + 31626247 = 31626524
331 + 31626193 = 31626524
571 + 31625953 = 31626524
607 + 31625917 = 31626524

Showing the first eight; more decompositions exist.
