Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503002, here are decompositions:

43 + 31502959 = 31503002
61 + 31502941 = 31503002
79 + 31502923 = 31503002
241 + 31502761 = 31503002
313 + 31502689 = 31503002
439 + 31502563 = 31503002
463 + 31502539 = 31503002
571 + 31502431 = 31503002

Showing the first eight; more decompositions exist.
