Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502204, here are decompositions:

43 + 31502161 = 31502204
73 + 31502131 = 31502204
373 + 31501831 = 31502204
397 + 31501807 = 31502204
463 + 31501741 = 31502204
571 + 31501633 = 31502204
673 + 31501531 = 31502204
757 + 31501447 = 31502204

Showing the first eight; more decompositions exist.
