Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502762, here are decompositions:

19 + 31502743 = 31502762
61 + 31502701 = 31502762
73 + 31502689 = 31502762
103 + 31502659 = 31502762
199 + 31502563 = 31502762
223 + 31502539 = 31502762
229 + 31502533 = 31502762
331 + 31502431 = 31502762

Showing the first eight; more decompositions exist.
