Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503062, here are decompositions:

103 + 31502959 = 31503062
109 + 31502953 = 31503062
139 + 31502923 = 31503062
181 + 31502881 = 31503062
373 + 31502689 = 31503062
499 + 31502563 = 31503062
523 + 31502539 = 31503062
631 + 31502431 = 31503062

Showing the first eight; more decompositions exist.
