Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503702, here are decompositions:

29 + 31503673 = 31503702
59 + 31503643 = 31503702
71 + 31503631 = 31503702
149 + 31503553 = 31503702
173 + 31503529 = 31503702
193 + 31503509 = 31503702
233 + 31503469 = 31503702
359 + 31503343 = 31503702

Showing the first eight; more decompositions exist.
