Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477102, here are decompositions:

3 + 31477099 = 31477102
23 + 31477079 = 31477102
281 + 31476821 = 31477102
359 + 31476743 = 31477102
479 + 31476623 = 31477102
491 + 31476611 = 31477102
509 + 31476593 = 31477102
593 + 31476509 = 31477102

Showing the first eight; more decompositions exist.
