Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536590, here are decompositions:

61 + 31536529 = 31536590
109 + 31536481 = 31536590
193 + 31536397 = 31536590
199 + 31536391 = 31536590
229 + 31536361 = 31536590
277 + 31536313 = 31536590
367 + 31536223 = 31536590
541 + 31536049 = 31536590

Showing the first eight; more decompositions exist.
