Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503762, here are decompositions:

11 + 31503751 = 31503762
13 + 31503749 = 31503762
29 + 31503733 = 31503762
89 + 31503673 = 31503762
131 + 31503631 = 31503762
193 + 31503569 = 31503762
233 + 31503529 = 31503762
293 + 31503469 = 31503762

Showing the first eight; more decompositions exist.
