Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562732, here are decompositions:

109 + 31562623 = 31562732
139 + 31562593 = 31562732
181 + 31562551 = 31562732
283 + 31562449 = 31562732
433 + 31562299 = 31562732
613 + 31562119 = 31562732
709 + 31562023 = 31562732
739 + 31561993 = 31562732

Showing the first eight; more decompositions exist.
