Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626282, here are decompositions:

53 + 31626229 = 31626282
73 + 31626209 = 31626282
89 + 31626193 = 31626282
151 + 31626131 = 31626282
173 + 31626109 = 31626282
229 + 31626053 = 31626282
241 + 31626041 = 31626282
263 + 31626019 = 31626282

Showing the first eight; more decompositions exist.
