Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476590, here are decompositions:

3 + 31476587 = 31476590
43 + 31476547 = 31476590
73 + 31476517 = 31476590
139 + 31476451 = 31476590
157 + 31476433 = 31476590
199 + 31476391 = 31476590
241 + 31476349 = 31476590
307 + 31476283 = 31476590

Showing the first eight; more decompositions exist.
