Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462526, here are decompositions:

19 + 31462507 = 31462526
163 + 31462363 = 31462526
457 + 31462069 = 31462526
523 + 31462003 = 31462526
547 + 31461979 = 31462526
577 + 31461949 = 31462526
607 + 31461919 = 31462526
709 + 31461817 = 31462526

Showing the first eight; more decompositions exist.
