Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477508, here are decompositions:

61 + 31477447 = 31477508
79 + 31477429 = 31477508
109 + 31477399 = 31477508
157 + 31477351 = 31477508
367 + 31477141 = 31477508
397 + 31477111 = 31477508
409 + 31477099 = 31477508
457 + 31477051 = 31477508

Showing the first eight; more decompositions exist.
