Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541602, here are decompositions:

5 + 31541597 = 31541602
11 + 31541591 = 31541602
173 + 31541429 = 31541602
359 + 31541243 = 31541602
461 + 31541141 = 31541602
563 + 31541039 = 31541602
641 + 31540961 = 31541602
971 + 31540631 = 31541602

Showing the first eight; more decompositions exist.
