Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615526, here are decompositions:

37 + 31615489 = 31615526
43 + 31615483 = 31615526
97 + 31615429 = 31615526
109 + 31615417 = 31615526
127 + 31615399 = 31615526
193 + 31615333 = 31615526
373 + 31615153 = 31615526
463 + 31615063 = 31615526

Showing the first eight; more decompositions exist.
