Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503076, here are decompositions:

23 + 31503053 = 31503076
83 + 31502993 = 31503076
113 + 31502963 = 31503076
149 + 31502927 = 31503076
179 + 31502897 = 31503076
389 + 31502687 = 31503076
587 + 31502489 = 31503076
593 + 31502483 = 31503076

Showing the first eight; more decompositions exist.
