Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502414, here are decompositions:

43 + 31502371 = 31502414
61 + 31502353 = 31502414
103 + 31502311 = 31502414
127 + 31502287 = 31502414
283 + 31502131 = 31502414
331 + 31502083 = 31502414
457 + 31501957 = 31502414
607 + 31501807 = 31502414

Showing the first eight; more decompositions exist.
