Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532060, here are decompositions:

139 + 31531921 = 31532060
151 + 31531909 = 31532060
421 + 31531639 = 31532060
433 + 31531627 = 31532060
577 + 31531483 = 31532060
607 + 31531453 = 31532060
643 + 31531417 = 31532060
661 + 31531399 = 31532060

Showing the first eight; more decompositions exist.
