Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502654, here are decompositions:

67 + 31502587 = 31502654
97 + 31502557 = 31502654
223 + 31502431 = 31502654
283 + 31502371 = 31502654
367 + 31502287 = 31502654
523 + 31502131 = 31502654
541 + 31502113 = 31502654
571 + 31502083 = 31502654

Showing the first eight; more decompositions exist.
