Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503236, here are decompositions:

7 + 31503229 = 31503236
19 + 31503217 = 31503236
97 + 31503139 = 31503236
277 + 31502959 = 31503236
283 + 31502953 = 31503236
313 + 31502923 = 31503236
379 + 31502857 = 31503236
547 + 31502689 = 31503236

Showing the first eight; more decompositions exist.
