Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503452, here are decompositions:

73 + 31503379 = 31503452
109 + 31503343 = 31503452
139 + 31503313 = 31503452
193 + 31503259 = 31503452
223 + 31503229 = 31503452
271 + 31503181 = 31503452
313 + 31503139 = 31503452
349 + 31503103 = 31503452

Showing the first eight; more decompositions exist.
