Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508852, here are decompositions:

61 + 31508791 = 31508852
139 + 31508713 = 31508852
181 + 31508671 = 31508852
283 + 31508569 = 31508852
409 + 31508443 = 31508852
523 + 31508329 = 31508852
541 + 31508311 = 31508852
619 + 31508233 = 31508852

Showing the first eight; more decompositions exist.
