Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502684, here are decompositions:

97 + 31502587 = 31502684
127 + 31502557 = 31502684
151 + 31502533 = 31502684
313 + 31502371 = 31502684
331 + 31502353 = 31502684
373 + 31502311 = 31502684
397 + 31502287 = 31502684
523 + 31502161 = 31502684

Showing the first eight; more decompositions exist.
