Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503434, here are decompositions:

73 + 31503361 = 31503434
97 + 31503337 = 31503434
103 + 31503331 = 31503434
283 + 31503151 = 31503434
331 + 31503103 = 31503434
373 + 31503061 = 31503434
577 + 31502857 = 31503434
673 + 31502761 = 31503434

Showing the first eight; more decompositions exist.
