Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503632, here are decompositions:

73 + 31503559 = 31503632
79 + 31503553 = 31503632
103 + 31503529 = 31503632
163 + 31503469 = 31503632
271 + 31503361 = 31503632
373 + 31503259 = 31503632
571 + 31503061 = 31503632
673 + 31502959 = 31503632

Showing the first eight; more decompositions exist.
