Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503032, here are decompositions:

73 + 31502959 = 31503032
79 + 31502953 = 31503032
109 + 31502923 = 31503032
151 + 31502881 = 31503032
271 + 31502761 = 31503032
331 + 31502701 = 31503032
373 + 31502659 = 31503032
499 + 31502533 = 31503032

Showing the first eight; more decompositions exist.
