Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503056, here are decompositions:

3 + 31503053 = 31503056
97 + 31502959 = 31503056
103 + 31502953 = 31503056
199 + 31502857 = 31503056
313 + 31502743 = 31503056
367 + 31502689 = 31503056
397 + 31502659 = 31503056
499 + 31502557 = 31503056

Showing the first eight; more decompositions exist.
