Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504376, here are decompositions:

3 + 31504373 = 31504376
19 + 31504357 = 31504376
73 + 31504303 = 31504376
157 + 31504219 = 31504376
193 + 31504183 = 31504376
523 + 31503853 = 31504376
577 + 31503799 = 31504376
643 + 31503733 = 31504376

Showing the first eight; more decompositions exist.
