Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503254, here are decompositions:

37 + 31503217 = 31503254
73 + 31503181 = 31503254
103 + 31503151 = 31503254
151 + 31503103 = 31503254
193 + 31503061 = 31503254
313 + 31502941 = 31503254
331 + 31502923 = 31503254
373 + 31502881 = 31503254

Showing the first eight; more decompositions exist.
