Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502394, here are decompositions:

23 + 31502371 = 31502394
31 + 31502363 = 31502394
41 + 31502353 = 31502394
61 + 31502333 = 31502394
83 + 31502311 = 31502394
107 + 31502287 = 31502394
151 + 31502243 = 31502394
181 + 31502213 = 31502394

Showing the first eight; more decompositions exist.
