Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562152, here are decompositions:

53 + 31562099 = 31562152
59 + 31562093 = 31562152
179 + 31561973 = 31562152
233 + 31561919 = 31562152
491 + 31561661 = 31562152
509 + 31561643 = 31562152
521 + 31561631 = 31562152
653 + 31561499 = 31562152

Showing the first eight; more decompositions exist.
