Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503060, here are decompositions:

7 + 31503053 = 31503060
67 + 31502993 = 31503060
97 + 31502963 = 31503060
101 + 31502959 = 31503060
107 + 31502953 = 31503060
137 + 31502923 = 31503060
163 + 31502897 = 31503060
179 + 31502881 = 31503060

Showing the first eight; more decompositions exist.
