Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459602, here are decompositions:

61 + 31459541 = 31459602
103 + 31459499 = 31459602
193 + 31459409 = 31459602
263 + 31459339 = 31459602
281 + 31459321 = 31459602
311 + 31459291 = 31459602
313 + 31459289 = 31459602
379 + 31459223 = 31459602

Showing the first eight; more decompositions exist.
