Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509060, here are decompositions:

7 + 31509053 = 31509060
29 + 31509031 = 31509060
31 + 31509029 = 31509060
43 + 31509017 = 31509060
61 + 31508999 = 31509060
101 + 31508959 = 31509060
113 + 31508947 = 31509060
139 + 31508921 = 31509060

Showing the first eight; more decompositions exist.
