Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503692, here are decompositions:

19 + 31503673 = 31503692
61 + 31503631 = 31503692
139 + 31503553 = 31503692
163 + 31503529 = 31503692
223 + 31503469 = 31503692
313 + 31503379 = 31503692
331 + 31503361 = 31503692
349 + 31503343 = 31503692

Showing the first eight; more decompositions exist.
