Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582602, here are decompositions:

13 + 31582589 = 31582602
43 + 31582559 = 31582602
71 + 31582531 = 31582602
89 + 31582513 = 31582602
113 + 31582489 = 31582602
131 + 31582471 = 31582602
193 + 31582409 = 31582602
199 + 31582403 = 31582602

Showing the first eight; more decompositions exist.
